Download or read book Optimizing the Performance of Synchronization Process written by Rshdee Alhakim and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: These works are in the theme of modelling and optimization of wireless communication systems used in particular in wireless sensor networks and indoor applications. In this area, the impulse-radio ultra-wideband (IR-UWB) technology is considered as a promising solution, because it offers significant potential in terms of fine time-domain resolution, low power and low cost on-chip implementation facility, high secure and safety, and its ability to coexist with narrowband systems. However, the timing synchronization process is still a major challenge that must be addressed in order to enable UWB transmission systems to reach a desired BER quality level. Synchronization systems are usually composed of three main units: signal detection, timing acquisition and tracking. The objective of this manuscript is to develop methods to control synchronization to optimize the quality of transmission of UWB signals. The timing with dirty template approach is proposed as a promising candidate for achieving rapid, accurate and low-complexity synchronization. The dirty template technique is utilized to develop and test the performance of the three aforementioned synchronization system units.

Download or read book Performance Evaluation of Multi User Uwb Communication Systems written by Murad Ali and published by LAP Lambert Academic Publishing. This book was released on 2011-05 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra wide-band is based on transmission with very short pulses of low energy.The wider bandwidth of UWB technology has several advantages such as excellent penetration ability, multi-user support and high channel capacity.UWB poses design challenges for low power and low complex systems at wider bandwidth.For digital systems, it also requires high sampling rate and intensive computation to estimate gain and delay of multi path channel. The performance of non-coherent transmitted reference (TR), frequency-shifted reference (FSR) and code- shifted reference (CSR) systems are compared with the orthogonal Gold code (OG) code reference (CR) systems for single and multiuser for low data rates. First, the performance of non-coherent receivers for single-user system working in residential LOS is evaluated.Secondly, the performance comparison of TR, FSR, CSR and OG-CR are presented in multiuser environment. The simulation results validate that CSR and OG-CR have better performance than TR and FSR in multiuser environment. Finally, results show that CSR shows better performance than OG-CR for few users and almost same performance as OG-CR at high SNR with more number of users.

Download or read book Performance Analysis and Effect of Multi user Interference for Ultra Wideband Communications written by Mukta Athavale and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-Wideband (UWB) is an upcoming technology for short-range high data rate applications like Wireless Personal Area Networks or medium/long-range low data rate applications like sensor networks. UWB has many captivating characteristics such as very short duration pulses (order of nanoseconds), multipath channel, large instantaneous bandwidth and time hopping pulse trains resulting in coexistence with the existing narrow band users. The Ultra Wideband communication systems employ the technique of Impulse radio of transmitting short duration pulses which result in extremely wide bandwidth and many performance benefits. Since UWB systems operate in dense multipath environments, RAKE receiver is the optimum choice for the receiver. Considering the evolving nature and the wide applications of this technology, it is important to analyze the system performance for different scenarios including the multi-user environment. My thesis mainly targets the analysis of the bit error rate (BER) performance of the time hopping pulse position modulation (TH-PPM) UWB system with the use of Ideal Rake Receiver and the performance degradation when the Selective and Partial Rake receivers are employed. I have also analyzed the effect of changing the repletion code length on the performance. The performance analysis is carried out for varying the modulation index M by employing 4-PPM instead of Binary PPM and simulation results show that 4-PPM offers a worse performance to the binary PPM case. Furthermore, I have evaluated the performance in the presence of Multiuser Interference using the Standard Gaussian Approximation. Finally, the performance of employing M-ary PPM in the multi-user scenario is also evaluated. The simulations are performed under the assumption of perfect channel knowledge. The IEEE UWB indoor channel model is used for Non Line of Sight (NLOS) Case C which is for 4 to 10 m distance between the transmitter and the receiver.
