摘要
本文讨论了软件实现卷极码堆栈译码算法中的几个主要问题.给出一种适于编程实现的路径量度表达式,实现了这种译码器的链表结构及限制译码中路径增长的方法,构造出编译码过程中的码树存贮表.
In this paper,we give a discussion on the software implementation of the Stack decoding algorithm for convolutional codes.A sort of path measurement representation suitable for programming is given.The chain-list constitution of this kind of decoder and the way to limit the increased path in the decoding process have been brought about.The code-tree memory list in the encoding and decoding process is strutted.
