Performance Analysis of Communication System with Convolutional Coding over Fading Channel

Multipath fading is a major problem of the wireless communication channel. To eliminate this fading problem and to have reliable communications in wireless channel, channel coding techniques are used. In this paper BER (bit error rate) performance is shown, by the means of Rayleigh and Rician multipath fading channels. Here the convolution encoding is used. The performance of convolution encoded binary phase shift keying (coded BPSK) and viterbi decoding is investigated. The performance of coded signal is better than uncoded signal. In this paper, how much improvement in BER is there when convolution code is employed for Rayleigh and Rician fading channel. Simulation results are shown graphically. Index Terms BER, BPSK, Convolution code, AWGN, Rayleigh multipath fading channel, Rician multipath fading, Viterbi decoding. ——————————  ——————————
