摘要

本文对波分复用(WDM)网络上的SPE-OCDMA(频谱相位编码光CDMA)进行了性能分析。利用离散时间马尔可夫链模型建立了多通道随机接入开槽Aloha的解析模型。WDM波长的个数对应于多通道开槽Aloha。我们测量了几个性能特征，即稳态吞吐量和平均数据包延迟时间。此外，还考虑了基于处理增益和波分复用波长数的系统效率。此外，指数重传用于解决分组冲突问题。在我们的数值结果中，系统性能是根据平均吞吐量和延迟时间给出的。

Performance analysis of SPE-OCDMA over WDM networks

This paper presents a performance analysis of SPE-OCDMA (spectrally phase-encoded optical CDMA) over WDM networks. The discrete time Markov chain model is used to build analytical model of multi-channel random access slotted Aloha. The number of WDM wavelength is corresponded to multi-channel slotted Aloha. We measure several performance characteristics, namely, steady-state throughput and average packet delay time. Additionally, the efficiencies of the system, which are based on both the processing gain and the number of WDM wavelengths, are considered. Additionally, exponential retransmission is used for solving packet collision problems. In our numerical results, system performance is given in terms of both average throughput and delay time.
