Abstract :
In this paper, we introduce a butterfly log-MAP algorithm to compute the parameters in systematic turbo code. It can efficiently reduce both the operations of computation and work units in the turbo decoder. In addition, we show the block diagrams of the proposed implementation in this paper.
