摘要
多用户干扰是影响OCDMA系统性能和用户数的主要原因,因此研究如何降低多用户干扰就显得尤其重要。文章在介绍了几种降低多用户干扰的常规方案及其性能的基础上,讨论了多用户检测技术OCDMA系统中的应用,并对泊松模型下利用干扰估计技术消除多用户干扰作了进一步的探索和分析。
In Optical Code Division Multiple Access (Optical -CDMA) systems, Optical Multiple Access Interference(OMAI) is the main factory witch affecting the performance of Optical - CDMA systems and the number of users, so it is very important to try our best to minimize OMAI. In this paper several routine solutions for reducing OMAI are introduced firstly, then the application of technology of Multi - User Detection for Optical - CDMA is discussed, and the further research in Poisson model of utilizing interference estimation to annihilate OMAI is given.
