Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In recent years, the research of integrated circuits for RF transceivers has been focussed on achieving higher level of integration. Since the successful of the implementation of monolithic transceivers, more and more attentions are drawn to the development of multi-standard transceivers for even higher level of system integration and flexibility to communicate using existing infrastructures when moving to different locations or when the access of networks using different communication standards is needed. While other multi-standard RF transceiver components are under intensive research, little attention is received for the multi-standard power amplifiers because of the power efficiency concerns and the very different specifications for power amplifiers using different standards. For an RF CMOS power amplifier, the problem is even more severe because of the intrinsic limitations of the process such as low breakdown voltage small transconductance compared to the other process. This work targets power amplifiers for IEEE 802.11 a/b/g because of their similar linearity and output power requirements. A broadband solution is proposed in this thesis. To date, most of the PA designs attempt to maximize the quality factor of the on-chip elements such as spiral inductors to minimize the power efficiency degradation while the others try to use bondwires or off-chip elements as a work around. This thesis attempts to describe a different approach by adopting Low-Q inductors to achieve broadband power amplification for multi standards with reasonable power efficiency performance. The basics, working principles, design, simulation and measurement result of the power amplifier as well as the performance comparison with the other power amplifiers in the literature and in the market are described in this dissertation.

Download or read book RF Analog Impairments Modeling for Communication Systems Simulation written by Lydi Smaini and published by John Wiley & Sons. This book was released on 2012-09-04 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growing complexity of personal mobile communication systems demanding higher data-rates and high levels of integration using low-cost CMOS technology, overall system performance has become more sensitive to RF analog front-end impairments. Designing integrated transceivers requires a thorough understanding of the whole transceiver chain including RF analog front-end and digital baseband. Communication system engineers have to include RF analog imperfections in their simulation benches in order to study and quantify their impact on the system performance. Here the author explores key RF analog impairments in a transceiver and demonstrates how to model their impact from a communication system design view-point. He discusses the design aspects of the front end of transceivers (both receivers and transmitters) and provides the reader with a way to optimize a complex mixed-signal platform by taking into account the characteristics of the RF/analog front-end. Key features of this book include: Practical examples illustrated by system simulation results based on WiFi and mobile WiMAX OFDM transceivers An overview of the digital estimation and compensation of the RF analog impairments such as power amplifier distortion, quadrature imbalance, and carrier and sampling frequency offsets An exposition of the challenges involved in the design of both RF analog circuits and DSP communication circuits in deep submicron CMOS technology MATLAB® codes for RF analog impairments models hosted on the companion website Uniquely the book bridges the gap between RFIC design specification needs and communication systems simulation, offering readers RF analog impairments modeling knowledge and a comprehensive approach to unifying theory and practice in system modelling. It is of great value to communication systems and DSP engineers and graduate students who design communication processing engines, RF/analog systems and IC design engineers involved in the design of communication platforms.

Download or read book Performance Analysis of IEEE 802 11g Receivers With Erasure Decoding to Mitigate the Effects of Pulse Noise Interference written by Georgios Zouros and published by . This book was released on 2006 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of IEEE 802.11g wireless local area network (WLAN) standard receivers when the signal is transmitted over a frequency-selective, slowly fading Nakagami channel in a pulse-noise interference environment when errors-and-erasures Viterbi decoding is used is examined. The different combinations of modulation (both binary and non-binary) and convolutional code rate specified by the WLAN standard are examined. The performance obtained with errors-and-erasures decoding (EED) is compared with the performance obtained with errors-only hard decision Viterbi decoding (HDD) as well as that obtained with soft decision Viterbi decoding (SDD) for binary modulation, while for non-binary modulation, EED performance is compared with HDD performance. It was found that EED can significantly improve performance under some conditions when pulse-noise interference is present.

Download or read book Design and Evaluation of TDMA Based IEEE 802 IIP Mac Protokol for Wireless Vehicular Communications written by Mahamat Ahmat Abakar and published by . This book was released on 2011 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Vehicular Communication (WVC) has been identified as a key technology for Intelligent Transportation Systems (ITS) for the past few years. IEEE 802.11p is the proposed standard for the physical and MAC layer of the WVC devices. The main objective of the standard is to change the frame format in order to increase the delay spread tolerance introduced by the vehicle mobility. To cope with this problem the channel bandwidth has been scaled to 20 MHz, rather than 10 MHz. This research proposes the TDMA technique with fixed time slots and a guard band between the slots to ensure interoperability between the wireless devices to communicate in rapidly changing environment where transactions must be completed in small timeframes. The new TDMA sub-layer is designed to be on top of the conventional 802.11p CSMA/CA MAC. This research work proposes a new design based on operation mode for IEEE 802.11p, in which the transmissions of data frames are initiated only by users. The results obtained reveal that the proposal achieves high and stable throughput, irrespectively of the number of contending and moving-away stations. It was found that 802.11p-based TDMA can achieve much higher throughput compared with the conventional 802.11p-based CSMA/CA, as the distance, vehicle speed and numbers increase. NS-2 simulation results present the performance analysis and validate the efficiency of the proposed scheme. For the packet loss comparison, it is also shown that IEEE802.11a achieved about 80% of packet loss, IEEE802.11p achieves about 70%, while the proposed TDMA achieves less than 10% of packet loss.
