摘要
文中首先简单地说明Viterbi译码算法原理,接着分析Viterbi译码算法设计及伪代码实现,然后根据软判决和硬判决对译码性能的影响以及改进的译码器和MATLAB库函数的译码器作了仿真比较。仿真表明:改进的译码器具有良好的性能。
In this paper, the principle of Viterbi is briefed first. Then the Viterbi decode design and Pseudo Code for the Viterbi Algorithm areanalyzed. Finally the capability of soft and hard decisions is compared, and the capability of ameliorated decoder and MATLAB library emulated. Simulations show that the ameliorated decoder is robust and of better performance.
