Abstract
Wireless communication systems with their vast development rely greatly on the modulation schemes and channel environments. Given the proper channel condition and modulation technique, information can be transmitted with ease and with negligible or no error. Thus, it is necessary to develop an efficient communication system to minimize errors during data transmission. The modulation techniques in communication systems have various performance characteristics such as power efficiency, bandwidth efficiency, and error rate. Some of the common modulation schemes are the M-ary Phase-Shift Keying (M-PSK) and M-ary Quadrature Amplitude Modulation (M-QAM). These techniques are used in the field of communication notably in wireless communication to test and evaluate the performance in fading channels. In this chapter, the Bit Error Rate (BER) performance of both M-PSK and M-QAM modulation schemes under the Additive White Gaussian Noise (AWGN), Rayleigh, and Rician fading channels has been compared. It was found M-QAM modulation scheme gives better performance in terms of data transmission rates and communication reliability when compared to M-PSK modulation scheme.
