摘要：
It is usually assumed that for implementing the maximum a posteriori (MAP) decoding algorithm, saving all the state metrics is required. This memory requirement makes the MAP an impractical decoding algorithm especially for the non-binary block codes. In this paper, we present a modification of the MAP algorithm, in order to make it a more feasible algorithm. The computational complexity analysis and the memory requirements as well as the simulation results for the proposed algorithm are presented.
