摘要
为了降低卷积码译码电路复杂度并获得较好的译码性能,设计了一种基于逻辑运算的卷积码译码方法,即利用异或逻辑运算的因果互换关系,实现卷积码译码重建。将该方法应用到(n,1,L)卷积码译码中,通过对几种常用的(n,1,L)卷积码进行译码仿真,证明该方法能顺利完成译码重建,且算法简单,易于实现。
In order to reduce the decoding complexity of convolutional codes and get better decoding performance,a decoding method for convolutional codes based on the logical operation is designed. Using the causal exchange relation of XOR logic operation the convolutional decoding reconstruction is realized. The method is applied to the decoding of( n,1,L) convolutional codes,and the simulation of several common(n,1,L) convolutional codes is carried out. The results show that the method can complete the decoding reconstruction smoothly,and the algorithm is simple and easy to implement.
