| Abstract: | Based on the technology of Turbo coding-decoding and Rician channel model,the applicability of Log-MAP and SOVA iterative decoding algorithm on Rician fading channels is analyzed in this article. The performance of this system using both Log-MAP and SOVA algorithm is simulated through Matlab. The results show that the Log-MAP algorithm has slightly higher BER results than SOVA on the correlated fading channels. |
