Paper Abstract

The symbol-by-symbol maximum a posteriori (MAP) known also as BCJR algorithm is described. The logarithmic versions of the MAP algorithm, namely, Log-MAP and Max-Log-MAP decoding algorithms along with a new Simplified-Log-MAP algorithm, are presented here. Their bit error rate performance and computational complexity of these algorithms are compared. A new hardware architecture for implementing the MAP-based decoding algorithms suitable for chip design is also presented here.
