Available in PDF, EPUB and Kindle. Book excerpt: Wireless channels are becoming more and more important, with the future development of wireless ad-hoc networks and the integration of mobile and satellite communications. To this end, algorithmic detection aspects (involved in the physical layer) will become fundamental in the design of a communication system. This book proposes a unified approach to detection for stochastic channels, with particular attention to wireless channels. The core idea is to show that the three main criteria of sequence detection, symbol detection and graph-based detection, can all be described within a general framework. This implies that a detection algorithm based on one criterion can be extended to the other criteria in a systematic manner. Presents a detailed analysis of statistical signal detection for digital signals transmitted over wireless communications Provides a unifying framework for different signal detection algorithms, such as sequence detection, symbol detection and graph-based detection, important for the design of modern digital receivers operating over mobile channels Features the hot topic of graph-based detection Detection Algorithms for Wireless Communications represents a novel contribution with respect to the current literature, with a unique focus on detection algorithms, as such it will prove invaluable to researchers working in academia and industry and in the field of wireless communications, as well as postgraduate students attending advanced courses on mobile communications.

Available in PDF, EPUB and Kindle. Book excerpt: Signal detection, parameter estimation and modulation classification are widely applied to many areas and plays a very important role in civilian and military, such as bio-science, criminal psychology, communication engineering, radar system, electronic warfare and so on. In the civilian field, with the increasing number of wireless electronic devices and higher transmission data rate demand, the problem of spectrum congestion becomes more and more highlighted and urgent. In recent years, wireless industry has shown great interest in Cognitive Radio (CR) and Dynamic Spectrum Access (DSA) network, whose primary function is to use limited frequency bands to transmit own signals without any interference with other primary users. Hence, the accuracy of signal detection and parameters estimation are particularly important and can provide reliable communication performance for cognitive radio users. In the military field, electronic warfare is crucial important part in modern war, such as own signal needs to be hidden, securely transmitted and received, enemy's signals need to be identified, located and jammed. Thus, in such a non-cooperative environment, signal detection, parameter estimation and modulation classification technologies become more and more important and challenging. In the past few decades, several signal detection methods have been proposed, such as energy-based detection, matched filter-based detection and cyclostationary feature based detection. Energy based detection is simple to implement, but poorly performing at low SNR. Although the matched filter-based detection is the optimal detector, it needs to accurately know the prior information of the detected signal. Hence, matched filter-based detection is impractical to implement in real environment, such as non-cooperative environment. Cyclostationary feature based signal detection has high computational complexity, but it can be used for high-precision signal detection in low SNR environments. In recent years, there are many researchers show their interest and effort in signal detection, parameter estimation and modulation classification technologies. Most of them are working with single signal detection, parameter estimation and modulation classification. A few people consider time and frequency mixed signals as their target signals. In particular, some people assume that there is no any overlap between co-exited signals in time domain and frequency domain. In such case, we can easily separate those co-existed signals with a band-pass filter in frequency domain. Meanwhile, we can easily know the number of co-existed signals, estimate each signal's parameters and classify their modulation types. However, in a spectrum congested environment, such as cognitive radio and electronic warfare, several signals are often mixed together with plenty of overlap in both time domain and frequency domain. In some special case, several signals are entirely overlapped in time domain and frequency domain, such as in-band full duplex communication signals. It is more challenge to enumerate and classify those kinds of mixed signals. Hence, studying mixed signal detection, parameter estimation and modulation classification is more practical significance. In this dissertation, we employ signal energy-based, mainly employ signal cyclostationary feature and machine learning technology-based methods to detect, estimate and classify mixed signal, which have significant overlap in both time domain and frequency domain. In particular, we employ energy-based detection to preliminary detect the signal is existed or not existed in the channel and use spectrum analysis roughly locate the interesting frequency band. Meanwhile, we employ different order signal cyclostationary features to detect, estimate and classify four popular digital communication signals, which includes low-order modulation type BPSK signal, high-order modulation type QPSK signal, 8-PSK signal and 16-QAM signals. According to our previous work, we can use second-order cyclostationary feature to detect and classify mixed signals, such as mixed BPSK signals, mixed QPSK signals. However, since some signals have no second-order cyclostationary feature, we unable to precisely estimate and classify them by using low order cyclostationary feature, such as we cannot use Spectral Correlation Function (SCF) to classify mixed QPSK signal and 16-QAM signal. So, in this dissertation, we consider some more challenged cases, include detecting, estimating and classifying mixed higher-order modulation signals, such as 16-QAM and 8-PSK signals, classifying mixed signals, which have similar cyclostationary features, such as QPSK and 16-QAM mixed signals, and analyze heavily overlapped mixed signals, such as two signals have same carrier frequency. Moreover, we employ low-order and high order cyclostationary features, i.e., cyclic moment and cyclic cumulants, to detect, estimate and classify more different combinations of mixed signals, such as BPSK and QPSK mixed signal, two QPSK mixed signal, BPSK and 16-QAM mixed signal, etc. In this dissertation, we also provide detailed performance analysis to demonstrate our proposed method can effectively detect mixed signals, estimate mixed signals' parameters, such as carrier frequency, symbol rate and power, and classify mixed signals' modulation types. In addition, our performance analysis is based on AWGN channel, flat fading channel and multi-path fading channels.

Book excerpt: A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference.

Book excerpt: Perception of human beings has evolved from natural biosensor to powerful sensors and sensor networks. In sensor networks, trillions of devices are interconnected and sense a broad spectrum of contexts for human beings, laying the foundation of Internet of Things (IoT). However, sensor technologies have several limitations relating to deployment cost and usability, which render them unacceptable for practical use. Consequently, the pursuit of convenience in human perception necessitates a wireless, sensorless and contactless sensing paradigm. Recent decades have witnessed rapid developments in wireless sensing technologies, in which sensors detect wireless signals (such as acoustic, light, and radio frequency) originally designed for data transmission or lighting. By analyzing the signal measurements on the receiver end, channel characteristics can be obtained to convey the sensing results. Currently, significant effort is being devoted to employing the ambient Wi-Fi, RFID, Bluetooth, ZigBee, and television signals for smart wireless sensing, eliminating the need for dedicated sensors and promoting the prospect of the Artificial Intelligence of Things (AIoT). This book provides a comprehensive and in-depth discussion of wireless sensing technologies. Specifically, with a particular focus on Wi-Fi-based sensing for understanding human behavior, it adopts a top-down approach to introduce three key topics: human detection, localization, and activity recognition. Presenting the latest advances in smart wireless sensing based on an extensive review of state-of-the-art research, it promotes the further development of this area and also contributes to interdisciplinary research.

Download or read book Mixed Signal Detection and Parameter Estimation Based on Second order Cyclostationary Features written by Dong Li and published by . This book was released on 2015 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signal detection and radio frequency (RF) parameter estimation have received a lot of attention in recent years due to the need of spectrum sensing in many military and civilian communication applications. In most of existing work, the target signal is assumed to be a single RF signal with no overlapping with other RF signals. However, in a spectrally congested and spectrally contested environment, multiple signals are often mixed together at the signal detector with significant overlap in spectrum. Conventional frequency analysis through Fourier transform is not capable of detecting mixed signals with significant spectral overlap. In this thesis, we first demonstrate the feasibility of using second-order cyclostationary feature to perform mixed signal detection. We then use the cyclostationary features to estimate the carrier frequencies of these mixed signals. Next, we extend our work to higher order modulation. We develop a robust algorithm to detect mixed signals and estimate their symbol rates as well as carrier frequencies via spectral coherence function (SOF) features. Furthermore, we evaluate the detection and estimation performances of the proposed algorithm in various channel conditions and signal mixture scenarios. Simulation results confirm the effectiveness of the proposed schemes.
