Performance Analysis of Selective Combining Diversity over Rayleigh Fading Channel in Wireless Communication

In this paper, we use the selective combining diversity over Rayleigh fading channel is presented. Different diversity techniques are available in the literature. Different techniques behave differently with different coding techniques. Here, diversity analysis of the Rayleigh fading channel is presented in Space time block codes (STBC). We are using the system model of the space time block codes to analysis the effect of diversity present in the wireless communication system. Bit error rate (BER) and signal to noise ratio (SNR) are the control parameters used to analysis the performance of selective combining diversity over Rayleigh fading Channel. Simulation result shows that the bit error rate versus EbNo is presented in presence of selective combining diversity in Rayleigh channel. Result also shows that the signal to noise ratio (SNR) goes on increases with the increase the number of receiver antenna. The result reveals that the wireless communication system has better performance when space time block coding (STBC) technique is used for receive diversity. Result shows that as the number of receiver goes on increases bit error rate also goes on decreasing.
