This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the license-free 60-GHz frequency band will allow multi-Gb/s data transmission over short distances. The design of these wireless communication systems strongly depends on the propagation channel. The objective of the thesis focuses on the multidimensionnal channel characterization to quantify at the end the contribution of multi-antenna techniques (MIMO) on the performance of communication. A wideband mm-W frequency channel sounder was developed and has allowed extensive indoor channel measurements. In order to compare experimental results with theoretical value, the ray tracing tool was improved. Taking into account the diffraction that takes place at the top of a rectangular obstacle, a new method based on a hybrid uniform theory of diffraction-physical optics has been proposed and validated. Experimental results had also allowed to quantify the diffuse parameters for materials usually found in indoor environments. It was shown that introducing the contribution of diffuse scattering improves the accuracy of the RT tool unlike what it can be found in the literature where an average diffuse scattering parameter is proposed for a given environment. Finally, based on the channel measurements, the performance of IEEE 802.15.3c MIMO-OFDM systems was performed and the results show that the use of antennas array at both the transmitter and receiver side could increase both the throughput by a factor of 3.7 and the communication distance by 1 meter.

Download or read book Advanced Trends in Wireless Communications written by Mutamed Khatib and published by IntechOpen. This book was released on 2011-02-17 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical limitations on wireless communication channels impose huge challenges to reliable communication. Bandwidth limitations, propagation loss, noise and interference make the wireless channel a narrow pipe that does not readily accommodate rapid flow of data. Thus, researches aim to design systems that are suitable to operate in such channels, in order to have high performance quality of service. Also, the mobility of the communication systems requires further investigations to reduce the complexity and the power consumption of the receiver. This book aims to provide highlights of the current research in the field of wireless communications. The subjects discussed are very valuable to communication researchers rather than researchers in the wireless related areas. The book chapters cover a wide range of wireless communication topics.

Download or read book Propagation Channel Characterization Parameter Estimation and Modeling for Wireless Communications written by Xuefeng Yin and published by John Wiley & Sons. This book was released on 2016-10-24 with total page 418 pages. Available in PDF, EPUB and Kindle. 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. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing
