摘要

Ｖｉｔｅｒｂｉ译码器中幸存路径存储管理一直沿袭两种传统方法─寄存器交换法与回索法。寄存器交换法内连线机制过于复杂，不利用大状态数译码器的硬件实现；回索法需采用大量额外存储单元作为缓冲，译码延迟亦较大。本文提出了一种幸存路径存储管理的新方法─寄存器／三态门回索法，结合了以上两种传统方法的优点，克服了它们的不足，极适合于Ｖｉｔｅｒｂｉ译码器的ＶＬＳＩ实现。

Abstract

There are two traditional techniques for the realization of survivor memory unit in Viterbi decoder-register exchange（RE）and trace back（TB）method.RE is not practical for the Viterbi decoder with large number of trellis states dut to the very complicated interconnections.TB needs a large quantity of buffers and has long decoding delay.In this paper a novel technique-register/three-state-gate trace back method is presented

which combines the advantages of both RE and TB and overcomes their disadvantages.It’s very suitable for VLSI implementation.
