将纠错编码(ECC)和素数跳频码技术结合起来,研究了基于纠错编码的多速率OCDMA系统的结构方案,并对未进行纠错编码的多速率OCDMA系统及经过纠错编码的多速率OCDMA系统的误码性能进行了模拟分析和比较。结果表明:如果两系统使用相同码长的光地址码,则经过纠错的编码系统同未经过纠错的编码系统相比,其误码率有了明显的改善;在保持两系统信息传输速率和码片间隔相等的条件下,恰当地选取纠错编码系统的码长,不仅误码性能可得到改善,而且可降低编码器和解码器的制作难度和成本。 Combining error correction coding (ECC) and prime frequency hopping code technology, the architecture of multi-rate OCDMA system based on error correction coding is studied. The multi-rate OCDMA system without error correction coding and multi-rate OCDMA The error performance of rate OCDMA system is simulated and compared. The results show that if the two systems use optical address codes of the same code length, the bit error rate of the error-corrected coding system is obviously improved compared with the one without error correction. While maintaining the transmission rate of the two system information, And the chip interval equal to the conditions, the appropriate choice of error correction coding system code length, not only can improve the error performance, but also reduce the encoder and decoder manufacturing difficulty and cost.
