适用于光码分多址通信系统的可调光编/解码器的一种新方案

A New Method of Tunable Optical Encoder/Decoder Using for Optical Code division Access Communication System

提出了一种新的可调光编/解码器的实现方案。这种新结构的可调光编/解码器与以前文献中提出的结构相比,大大减少了所用2×2光开关数及光纤延时线的条数和长度,减小了硬件实现的复杂性,降低了成本和功耗,便于集成。

A new tunable optical encoder/decoder structure is proposed In contrast to the previous structures reported in the literature, the new structure has greatly reduced the number of optical switches and fiber optic delay lines, and the length of fiber optic delay line used It is shown that the hardware complexity, the cost and the power loss of the new structure can be greatly reduced It is easy to integrate
