摘要 光多址干扰是影响时域振幅编码和跳频扩时OCDMA系统误码率和用户数的主要原因。该文分别在时域振幅编码和跳频扩时两种OCDMA系统中对光多址干扰问题进行研究,提出通过改良码系采用色散管理的技术、选用适当的线路码及合理使用光限幅器等方法来减小光多址干扰。 In time-amplitude encoding and frequency hopping/time-spreading OCDM system, OMAI is the main factory witch affecting the BER and number of users.This paper is about how to decrease OMAI in these two system with technologies of improving code series, managing Dispersion,selecting line-code and proper using hard-limiter.
