BER Performance using BPSK Modulation over Rayleigh and Rician Fading Channel

In modern mobile communication, it is important to provide finer as well as productive facility to all the mobile users through improved communication system. In this paper, binary phase shift key (BPSK) modulation is utilized by almost all base stations for their operation to send/receive voice/data over long distance. BPSK modulation technique is one of the efficient modulations in terms of power which requires minimum power during their operation. In this paper, the performance of mobile communication system has been compared over Rayleigh and Rician fading channel in terms of bit error rate (BER). During the transmission of information first Rayleigh fading channel has been considered and then after Rician fading channel to see the effects. The simulation of analytical expression has been performed to determine the BER over these two channels and obtained results has been shown between the BER and transmitted power of the signal. These results show BER response against transmitted power over Rician channel is better as compared with Rayleigh fading channel. Analytical results are verified by using MATLAB simulation.
