摘要
描述了CO-OFDM系统的实验平台,通过实验验证了在CO-OFDM传输系统中使用QC-LDPC的编码方案,分别分析了LDPC码在编码长度为960和2304、编码速率为50%和75%的情况下,对单个子载波误码率以及所有子载波平均误码率的影响,同时也验证了UMP BP-based解码算法。
This paper describes the experimental platform of CO-OFDM system, the encoding scheme using QC-LDPC in CO-OFDM transmission system is verified by experimental results, when the LDPC code in the encoding length of 960 and 2304, encoding rate of 50% and 75% respectively, the bit error rate of each sub- carrier and the average bit error rate of all subcarriers are analyzed, the UMP BP-based decoding algorithm are also verified.
