BER Analysis of Multiple Input Single Output System for BPSK Modulation in Rayleigh Channel

Abstract

This paper addresses the important BER analysis for MRC and Alamouti Space Time Block Coding (STBC) for different no. of transmitter and different no. of receiver. Recall, some basic important terms i.e. three receive diversity schemes – Selection combining, Equal Gain Combining and Maximal Ratio Combining. All the three approaches used the antenna array at the receiver to improve the demodulation performance, albeit with different levels of complexity. Time to move on to a transmit diversity scheme where the information is spread across multiple antennas at the transmitter. In this paper, discuss a popular transmit diversity scheme called Alamouti Space Time Block Coding (STBC). For this discussion, Technique assumes that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.
