介绍用于光纤通信的速率为2.5 Gb/s的高速RS(255,239)译码器设计。对输入信号中可能出现的超

出译码器纠错能力的误码可进行检测判断,保证了误码不扩散。对译码器中大量使用的有限域乘法器进行了优化设计,尤其对并行钱氏搜索电路中的乘法器采用了按组优化设计方法,与直接实现方法相比,复杂度降低了45 -For optical fiber is introduced at a rate of 2.5 Gb/s (255239) of the high speed RS decoder design. Of the input signal of possible super

Out of the error correction decoder ability can detect judgment, to ensure the error non-proliferation. To use a lot of decoder limited domain on time-multiplier, the optimization design, especially for parallel once in the circuit on time-multiplier search by the group of optimization design method, and the direct method, compared to 45　lower complexity
