摘要
网格编码调制(TCM)是一种将编码和调制相结合,利用信号集的冗余度来获取纠错能力的技术。而用于卷积码的维特比译码器同样可以用作基于卷积码和PSK的TCM的译码。本文提出了一种适用于TCM的全并行的维特比译码的设计方案,并在Xilinx公司的v600ebg432-8上实现。
TCM, namely trellis coded modulation is the technology which can combine coding and modulating and make use of the redundancy of signal sets to acquire the error-correcting capability. The Viterbi decoder for the convolution code can be also used in the decoding of TCM based on convolution and PSK. A design of all-parallel Viterbi decoder applicable for TCM is put forward in this paper and has been implemented with Xilinx＇s FPGA v600ebg432-8.
