TCM 복호기의 ACS 다중화 및 생존경로척도 기억장치 관리 방법
A Method of Multi-processing of ACS and Survivor Path Metric Memory Management for TCM Decoder
초록
TCM offers considerable coding gains without compromising bandwidth or signal power. But TCM decoder is more complex than convolutional Viterbi decoder. Because, the number of branches exponentially increased by the constraint length and input symbol bits. The parallelism of ACS and memory management technique of SPMM is one of the important factor for speed-up and hardware complexity. This paper proposes a multi-processing technique of ACS and also gives a memory management technique of SPMM in TCM decoders.
