| 摘 要： | 多用户干扰(multiple access interference,MAI)一直是光码分多址通信系统所要解决的关键技术之一,基于平衡检测法的光谱幅度编码(spectral amplitude coding,SAC)方案的提出能够有效地消除MAI.该文介绍了平衡检测法的原理并将其应用到光谱幅度编码系统中,并应用光通信仿真软件Optisystem7.0对该系统进行了仿真,仿真结果直观地表明,该系统实现了在BER≤10-9时的无误传输,即消除了MAI.

| Abstract: | Multiple access interference (MAI)is always one of the main problems to be solved in the system of optical CDMA(OCDMA). The proposal of SAC-OCDMA based on balanced detection can effectively suppress MAI. This paper presents the theory of balanced detection and its application to SAC(spectral-amplitude-coding). Optisystem 7.0,the simulation software for optical communication,was used to simulate the system. The result of simulation obviously indicates that this system can transfer data inerrably at BER=10-9,... |
