A Signal Integrity Based Rate Adaption Algorithum available in PDF, EPUB and Kindle. Wireless systems have gained momentum in recent years due to ease, universality and cost reduction. In a wireless network the signal degradation is time variant based on environmental factors. As variations in signal quality and interference from external sources affect the network, it is necessary and important to adapt the rate to the channel conditions via a rate adaptation algorithm driven by changes in the signal quality. This research addresses signal integrity in a local area network and proposes a rate adaptation algorithm for 802.11 wireless networks based on signal quality and packet error rate. The relationship between signal strength and packet error rate is analyzed and a new rate adaptation algorithm for 802.11n is presented. The algorithm developed in this thesis effectively adapts the rate to minimize packet error rate while it maximizes throughput. Through experiments, it has been shown that the proposed algorithm achieves better throughput compared to state of the technology rate adaptation algorithms currently implemented in commercial 802.11n systems.

Download and read online ebook Advanced Signal Integrity for High-Speed Digital Designs write by Stephen H. Hall. This book was released on 2011-09-20. Advanced Signal Integrity for High-Speed Digital Designs available in PDF, EPUB and Kindle. A synergistic approach to signal integrity for high-speed digital design This book is designed to provide contemporary readers with an understanding of the emerging high-speed signal integrity issues that are creating roadblocks in digital design. Written by the foremost experts on the subject, it leverages concepts and techniques from non-related fields such as applied physics and microwave engineering and applies them to high-speed digital design—creating the optimal combination between theory and practical applications. Following an introduction to the importance of signal integrity, chapter coverage includes: Electromagnetic fundamentals for signal integrity Transmission line fundamentals Crosstalk Non-ideal conductor models, including surface roughness and frequency-dependent inductance Frequency-dependent properties of dielectrics Differential signaling Mathematical requirements of physical channels S-parameters for digital engineers Non-ideal return paths and via resonance I/O circuits and models Equalization Modeling and budgeting of timing jitter and noise System analysis using response surface modeling Each chapter includes many figures and numerous examples to help readers relate the concepts to everyday design and concludes with problems for readers to test their understanding of the material. Advanced Signal Integrity for High-Speed Digital Designs is suitable as a textbook for graduate-level courses on signal integrity, for programs taught in industry for professional engineers, and as a reference for the high-speed digital designer.

Download and read online ebook Analog-and-Algorithm-Assisted Ultra-low Power Biosignal Acquisition Systems write by Venkata Rajesh Pamula. This book was released on 2019-01-02. Analog-and-Algorithm-Assisted Ultra-low Power Biosignal Acquisition Systems available in PDF, EPUB and Kindle. This book discusses the design and implementation aspects of ultra-low power biosignal acquisition platforms that exploit analog-assisted and algorithmic approaches for power savings.The authors describe an approach referred to as “analog-and-algorithm-assisted” signal processing.This enables significant power consumption reductions by implementing low power biosignal acquisition systems, leveraging analog preprocessing and algorithmic approaches to reduce the data rate very early in the signal processing chain.They demonstrate savings for wearable sensor networks (WSN) and body area networks (BAN), in the sensors’ stimulation power consumption, as well in the power consumption of the digital signal processing and the radio link. Two specific implementations, an adaptive sampling electrocardiogram (ECG) acquisition and a compressive sampling (CS) photoplethysmogram (PPG) acquisition system, are demonstrated. First book to present the so called, “analog-and-algorithm-assisted” approaches for ultra-low power biosignal acquisition and processing platforms; Covers the recent trend of “beyond Nyquist rate” signal acquisition and processing in detail, including adaptive sampling and compressive sampling paradigms; Includes chapters on compressed domain feature extraction, as well as acquisition of photoplethysmogram, an emerging optical sensing modality, including compressive sampling based PPG readout with embedded feature extraction; Discusses emerging trends in sensor fusion for improving the signal integrity, as well as lowering the power consumption of biosignal acquisition systems.

Download and read online ebook Advanced Concepts in Adaptive Signal Processing write by W. Kenneth Jenkins. This book was released on 2012-12-06. Advanced Concepts in Adaptive Signal Processing available in PDF, EPUB and Kindle. Although adaptive filtering and adaptive array processing began with research and development efforts in the late 1950's and early 1960's, it was not until the publication of the pioneering books by Honig and Messerschmitt in 1984 and Widrow and Stearns in 1985 that the field of adaptive signal processing began to emerge as a distinct discipline in its own right. Since 1984 many new books have been published on adaptive signal processing, which serve to define what we will refer to throughout this book as conventional adaptive signal processing. These books deal primarily with basic architectures and algorithms for adaptive filtering and adaptive array processing, with many of them emphasizing practical applications. Most of the existing textbooks on adaptive signal processing focus on finite impulse response (FIR) filter structures that are trained with strategies based on steepest descent optimization, or more precisely, the least mean square (LMS) approximation to steepest descent. While literally hundreds of archival research papers have been published that deal with more advanced adaptive filtering concepts, none of the current books attempt to treat these advanced concepts in a unified framework. The goal of this new book is to present a number of important, but not so well known, topics that currently exist scattered in the research literature. The book also documents some new results that have been conceived and developed through research conducted at the University of Illinois during the past five years.
