An Improved Log-MAP Decoding Algorithm
This paper mainly discusses the time-delay problem of Turbo decoding algorithm, and an improved Log-MAP decoding algorithm is proposed. This algorithm reduces the amount of computation of the whole decoding process by introducing a matrix named Matrix to reduce the repeated numerical computation in the process of the iterative decoding. The improved algorithm is simulated and compared the complexity with Log-MAP algorithm. The result of simulation shows that the improved algorithm obtains a- same bit error performance to the Log-MAP algorithm, it also reduces the complexity of the algorithm and speeds up the decoding process, reduces the time-delay greatly.
