Abstract
Title: ON IMPORTANCE OF BIT ERROR RATE IN WIRELESS COMMUNICATION
Authors: Mr. Rajesh Goel, Mr. Mukesh singla, Dr. Pawan Kumar Bansal
Abstract:
This "Letter" compares the six PSK based digital transmission schemes PSK, QPSK, OQPSK, MSK, GMSK, and QAM[1,2,3]. The comparison proposes that Bit Error Rate is the fundamental parameter to access the quality of any digital transmission .By describing the basic existing configurations [2, 3] and the characteristics of their transmitters and receivers, through matlab; we have evaluated them by computer simulation. By comparison, it is observed that different modulation techniques struggles neck to neck for getting low BER ,but still with the slight change in BER the quality changes many folds(figure's). If these PSK techniques are used in designing the wireless transmitter, then BER further increases due to system complexity. Therefore there is a requirement of designing the new applications/transmission system having the basis as PSK modulation, so that BER atleast remains constant, if not decreases
