Abstract :

Turbo codes are the forward error correction codes widely used in wireless communication system for obtaining a maximum throughput. Turbo codes offer a coding gain close to Shannon limit with a reducible bit error rate in case of performance. In this paper a turbo decoder is implemented with different decoding techniques. The MAP, Log-MAP and Max-Log-MAP are implemented to recover the original information. The BER performance for different channel conditions has been tested for various decoding algorithms. The results of all decoding techniques are compared so as to achieve a maximum throughput by selecting a relative decoder.
