| Abstract: The interleavers used in Turbo codes play a major role in the performance of turbo codes. Therefore, it is necessary to design turbo codes with good interleaver structure. In this paper the performance of Turbo codes for proposed interleaver was analyzed in terms of the bit error rate (BER) Vs Eb/No for SOVA(Soft Output Viterbi Algorithm) and MAP (Maximum A Posteriori Probability) decoding algorithms and compared with the result for block interleaver and random interleaver. This proposed interleaver uses the hamming weight as a design criterion to improve the performance of the turbo codes. The channel is subjected to Additive White Gaussian Noise (AWGN) in terms of the Signal to noise ratio (Eb/N0) in db. Moreover, Comparison between the proposed interleaver to block interleaver and ordinary random interleaver will be made. | ||||
