A transformation for computational latency reduction in turbo-MAP decoding

The SOVA and the log-MAP are commonly used in turbo decoding. In this paper, we propose to modify the sliding window MAP-algorithm in [5]to reduce the computational delay even further. We compare the simulation performance of this low latency log-MAP algorithm with the sliding window log-MAP. We also estimate the VLSI implementation complexities of the SOVA, the log-MAP and the proposed low latency log-MAP.
