摘要
一种基于AWG的OCDMA系统编解码方案,采用二维RS码序列地址码对宽带非相干光源的谱域进行域编。通过利用二维RS码字的周期性和AWG路由器的循环性,系统所用的编解码器能够同时对不同用户的地址码进行编解码。在解码端,先对编码信号在时域解码,补偿编码信号的时域延迟,再在频域用平衡检测原理进行相关解码输出,恢复传输的数据比特。
A scheme of system coding and decoding based on AWG and OCDMA realized through follow steps： adopt sequence code based on planar RS code to translate and edit chart field of wide-band non-coherent lamp-house; through the periodicity of planar RS code and the cyclicity of AWG router, the coder and decoder system uses can operate address code of different users synchronously. At the decoding end, first decode the coding signal in the right time field, and Compensate the time delay of the decoding signal, then transmit the related decoding code in the channel field with the checking theory. Finally, resume the date bate in transmitting process.
