Differential Qpsk Based Communication System

This book can be used as a guide for building a digital communication system using digital signal processor.In this book, digital and analog modulation techniques are explained using plots. Differential Quadrature Phase Shift Keying Transmitter and Receiver block level designs are explained using practical results.The aim of this project is to implement a Differential Quadrature Phase Shift Keying based communication system on the Texas Instruments TMS320C6713 digital signal processor . In this communication system, at transmitter and receiving side root raised cosine pulse shaping technique is used to reduce Inter symbol Interference. At receiver side we have to recover deferentially modulated signal and have to do Symbol Synchronization. For symbol synchronization we have used Gardner's Algorithm.
