| Abstract: | The performance of MAP decoding algorithm is optimal, but its complexity is very high, which affects its implementation in fact. This paper introduces a new decoding algorithm with the performances similar to that of MAP algorithm and with lower complexity, and makes it more perfect .The simulation results show that the new SOVA algorithm performs very close to the MAP algorithm for binary turbo codes. |
