一种用FPGA实现BCH(31,21)编/解码的方法
Method of Coding the BCH(31,21) with FPGA
本文简要介绍了二元BCH码的一般原理并分析了二元BCH码的编码和解码的理论基础和串/并行编码方法及代数译码、非代数译码的概念，分析了二元BCH码的检错和纠错能力，主要给出了一种用FPGA实现二元BCH(31,21)码的并行编码与伴随式译码的解决方案，还给出了用这种方法实现的编解码器的部分仿真结果。
In this paper, we briefly studied the encoding and decoding theory of the BCH codes, discussed two coding methods, which are encoding-parallel and coding-serial, and two arithmetic methods for decoding, algebraic method and non-algebraic method. And studied the finding and correcting errors capability of the BCH code. At the same time, we offered the parallel coder and the syndrome decoder, which are for the BCH(31,21) codes and implemented with the FPGA. And we also gave out their simulation.
