摘　　要：本文以FPGA为基础,针对IEEE802.16d协议,对协议规定的信道编译码的原理和FPGA实现算法进行简要说明,并对算法进行了部分优化,达到节省硬件资源、提高系统的可靠性和有效性的目的。在此基础上进行了Matlab仿真,绘出了信噪比与误码率的曲线图并与理论仿真图对比。为FPGA实现信道编译码提供了理论基础,有一定的借鉴意义。This paper was based on FPGA, according to IEEE802.16d protocol the principle of the channel coding and decoding that provided with IEEE802.16d protocol and FPGA algorithm were briefly described, The optimization of algorithm was made partly to save hardware resource, improve the reliability and validity of system. Based on that, it was drew the curve of the signal to noise ratio and bit error rate, and compared it with theoretical simulation by Matlab. This paper provided theoretical basis and had certain reference significance for FPGA implementation of channel coding and decoding.
