摘　　要：提出了一种能实现光CDMA通信的可调光正交码编 /解码器的方法。该方案基于传统的“并 -串式”可调光正交码编 /解码实现方案[1] ,并力求减少编解码器中的电光开关的数目以降低成本和损耗 ,具有结构简单、使用灵活方便、光功率损耗低、便于集成等优点 ,广泛适用于全光码分复用通信系统。An improved method for implementing tunable opt ical orthogonal code encoder /decoder is put forward.The proposed scheme is base d on th e traditional parallel-serial-based scheme in an attempt to reduce the number of electro-optic switches.The configuration of the proposed encoder/decoder is simple and flexible.In addition,it has low optical power loss an d very suitabl e for all-optical code division multiplexing communication systems.
