Abstract

To deal with n numbers of user simultaneously and error free communication with maximum utilization of limited spectrum, BER(bit error rate) improvement is an open challenge for communication engineers. In this paper work is an attempt to implement such an error control code Turbo code in which BER improve by using various efficient encoding and decoding designs. Turbo code provides modest decoding complexity for large block length and better bit error rate as compared to other code. According to [7] RSC encoder provides minimum error probability is implemented. For testing AWGN wireless channel is used. Recursive structure along with BPSK modulation is used. The decoding algorithm such as Viterbi algoritm,MAP(maximum a posterior),BCJR (bahl, cocke, jelinek and raviv)can be used .
