摘要

摘要: 分析了里德-所罗门码(RS码)的误码率性能,提出了一种基于RiBM算法的RS(15,9)译码器。该译码器采用流水线结构,通过RiBM算法求解关键方程,在此基础上将高斯加性白噪声(AWGN)引入光纤模拟大气激光通信系统,并在现场可编程门阵列(FPGA)平台上完成了测试。测试结果表明:提出的译码器译码速率达到1.11 Gbit/s,为Altera IP核的3.54倍。RiBM算法具有硬件复杂度低、关键路径延时短的优点,能满足系统译码的要求。

Abstract: To improve communication quality and meet the reliability requirement of data transmission, the Bit Error Rate(BER) performance of Reed-Solomon(RS) codes is analyzed, and a RS(15,9) hardware decoder based on Reformulated Inversionless Berlekamp-Massey(RiBM) algorithm is proposed. The decoder operates in pipeline architecture, and its key equation is resolved by the RiBM algorithm. On that basis, an atmospheric laser communication system is simulated by adding Additive White Gaussian Noise(AWGN) in a fiber, and it is tested on a Field Programmable Gate Array(FPGA) platform. The experimental result shows that decoding speed can be up to 1.11 Gbit/s, as 3.54 times as that of Altera's IP core. The RiBM algorithm has advantages of low hardware complexity and short critical path delay, and can meet the demands of the decoding system.
