Now-a-days, wireless communications gets more attention from the Communication industry and provide quality information transfer between portable devices.Applications like Autonomous sensor networks, Multimedia, Videoconferencing, and Distance learning and Internet enabled cell phone are developed by 3G system. Also Long Term Evolution (LTE) is going to increase the data rate, throughput, decrease latency, etc, for the above applications and also to bring lot of applications. Our primary aim of this book is to minimize the error probability of a LTE system and to bring the spectrum efficiency...

In this work, a comprehensive review on Photoplethysmography, its clinical applications and the analysis of PPG signals are given. Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the micro vascular layer of tissue. Mostly it is used as a non-invasive technique to make measurements at the skin surface. Five known PPG recordings are studied. Chapter 1 reviews the PPG signals as a marker for clinical applications. Chapter 2 emphasizes the review on PPG analysis with respect to the Heart Rate Turbulence and Ventricular...
