摘要
卷积码的Viterbi译码算法已经被广泛地应用到通信和信号处理的各个领域.为了兼顾性能和面积,文中设计的(2,1,7)卷积码的Viterbi译码器采用串并结合的方式,对译码器的核心部分加比选单元作出了较大改进,在性能和资源的占用等方面较传统的译码器有了较大改善.
Convolutional code and its Viterbi decoding algorithm had been widely applied to various fields of communication and signal processing. This paper presents the decoding scheme of （2,1,7） convolutional code. In order to take both speed and size into account, the decoder combines parallel structure with serial structure. The core part of the decoder, Add-Compare-Select Unit, has been improved greatly, and the whole decoder has the advantages of performance and resource expense than traditional Viterbi decoder.
