摘　　要：分析了目前存在的编解码器的优缺点 ,提出一种可调串行全光码分多址 (CDMA)编解码器。根据其工作原理 ,推导其最佳设计参数 ,并进行功能仿真 ,验证了该编解码器的正确性及可实现串行编解码、地址码可调、编解码器一体、既可用于同步码分多址又可用于异步码分多址通信等特点。Encoder and decoder for optical code division multiple access is the key technique of the realization of optical code division multiple communication system. A tunable serial encoder/decoder for optical code division multiple accesses is presented. Fundamental is analyzed. Optimal parameters for designing it are derived, and function simulation is done. The encoder/decoder features that encoding/decoding is done serially, address codes can be tunable, encoder and decoder can be in one unit and it not only can be used in synchronous optical CDMA system but also can be used in asynchronous optical CDMA system. Therefore, it possesses some degree of practical value.
