摘 要: | BCH码由于编译码简单、纠错性能好而广泛应用于工程实践中。文章从传统编译码方法的原理、性能、优缺点及应用情况出发,推导出一种缩短BCH码(16,8,5)的查表编译码方法。经过VHDL仿真验证,该方法简单实用,占用硬件资源少,是工程实践中一种较好的方法。

Abstract: | BCH Code is widely used because of its simplicity and good performance.In this paper a coding and decoding algorithm called look-up table is introduced based on the principle,performance and usage of BCH codes.Finally this method is validated by VHDL simulation. |
