二维光码分多址系统及其编/解码器设计

Two-dimensional Optical CDMA Networks and the Design of Encoder/Decoder

介绍时间和空间(T/S)、波分和码分(WDM+OCDMA)、跳频和码分(FH+OCDMA)3种二维光码分多址编码方案.利用光纤延迟线和波分解复用器构造出一种波长可调的二维编/解码器,该方案以光纤延迟线编/解码器为基础,引入波分解复用器实现波长域编码,具有构造简单、变址灵活等优点.

Three schemes of constructing 2D OCDMA access networks are introduced, which deploy the technologies of Time/Space,WDM+OCDMA and FH+OCDMA. In addition, we propose to construct 2D encoder/decoder on the basis of optical delay lines and wavelength division demultiplexer,which can be implemented easily and has much maneuvrability in selecting address.
