提出了基于RS码(Reed-Solomon Code)的光码分多址(OCDMA)系统的前向纠错编码方案,仿真分析了该方案对一维、二维OCDMA系统的纠错能力。研究结果表明:对于相同码长、相同码重光地址码的OCDMA系统,采用前向纠错(FEC)技术能够有效降低系统误码率,提高系统容量,改善系统性能。对于来自同一码族的OCDMA系统,随码重增加,系统性能改善越好。 A forward error correction coding scheme based on Reed-Solomon Code for optical code division multiple access (OCDMA) system is proposed. The error correction capability of this scheme for one-dimensional and two-dimensional OCDMA systems is simulated. The results show that for the OCDMA system with the same code length and same optical code, the FEC technology can effectively reduce the system error rate, increase the system capacity and improve the system performance. For OCDMA systems from the same code family, as system weights increase, system performance improves better.
