| Popis: | 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. |
