Performance Analysis of Normalized Throughput in a Hybrid WDMA-OCDMA System

理论分析了一种混合WDMA OCDMA系统的归一化吞吐量性能研究了光差拍噪声对系统归一化吞吐量性能的影响 提出了BCH信道编码的方案来改善系统性能 结果表明,当系统负载较轻时,归一化吞吐量略微下降;但当系统负载中等或较重时,归一化吞吐量明显提高 同时,BCH信道编码提高了WDMA

The performance of normalized throughput in a hybrid WDMA-OCDMA system is studied. The effect of optical beat noise on the normalized throughput is analyzed. The scheme of BCH channel coding is proposed to improve the performance of a hybrid WDMA-OCDMA system. The analysis result shows that the normalized throughput is a little decreased when traffic load is light, but can improved greatly when traffic load is medium and heavy. Furthermore, the maximum normalized throughput will increase for the BCH-coded hybrid WDMA-OCDMA system.
