Abstract
In this paper, an analytical result of bit error probability of 2-state convolutional code with log-maximum a posteriori probability (Log-MAP) decoding algorithm with hard decision are presented. The result shows that the error performance of Log-MAP decoding is slightly better than both Max-Log-MAP decoding and Viterbi decoding. Furthermore, the analytical result of bit error probability of 4-level soft decision Log-MAP decoding is shown.
