摘要
介绍了卷积码的线性离散时不变系统模型。从建立卷积码的状态变量方程出发,研究了卷积码的代数结构,并详细论述了基于状态变量方程描述的迭代译码算法。
This paper presents a model of discre te linear time -invariable system fo r convolutional code.Beginning fro m the foundation of state -variable eq uation,the algebraic structure of c onvolutional code is examined and an iterative algorithm based on representation of state -variable equation is discussed in deta il.
