BER Analysis of BPSK Modulation Scheme for Multiple Combining Schemes over Flat Fading Channel

Abstract

Focus of the study was to provide error-free communication in mobile communication with higher data rates, spectral efficiency, and energy efficient. Basically, work was done to investigate the performance of the Binary Phase Shift Keying (BPSK) modulation technique for multiple combining schemes and the behavior of signal in wireless communication where multipath propagation and uncertainty in the system. We use the Multiple-input Multiple-output (MIMO) and antenna diversity to get many copies of the same signal; some of them were faded, but some had sufficient information. Then the next step was to combine or select the best signal to achieve the optimum results from them. Moreover, the Bit Error Rate (BER) of multiple combining schemes for 2*1 and 2*2 were found and the results of each combining scheme were compared. Later on, the comparison of these combining schemes was collectively represented; it is very important because getting the required data from the received copies of the same signal is not easy.
