Efficient Method to Implement Max-Log-MAP Algorithm: Parallel SOVA  

Lee, Chang-Woo (School of Information, Communications and Electronics Engineering, The Catholic University of Korea)
Abstract
The efficient method to implement the Max-Log-MAP algorithm is proposed by modifying the conventional algorithm. It is called a parallel soft output Viterbi algorithm (SOVA) and the rigorous proof is given for the equivalence between the Max-Log-MAP algorithm and the parallel SOVA. The parallel SOVA is compared with the conventional algorithms and we show that it is an efficient algorithm implementing the modified SOVA in parallel.
