| 摘 要： | 基于扩展二次同余码/单重合序列(EQC/OCS),利用光纤布拉格光栅(FBG)和光纤延迟线作为编解码器,对二维非相干光码分多址(OCDMA)系统进行系统仿真。通过软件仿真,实现了4个用户的EQC/OCS码字的解码相关输出结果。结果表明,低成本的FBG编/解码器实现了EQC/OCS码字的编码和相关解码,提高了二维OCDMA系统容量。

| Abstract: | Based on extended quadratic congruencies code/one coincidence sequence(EQC/OCS) the incoherent 2-D optical code-division multiple access system(OCDMA) is simulated by using fiber Bragg grating(FBG) and fiber delay line.The expected en/decoding result with four users is obtained by system simulation.It is indicated that the low cost FBG can be employed as en/decoder for EQC/OCS code,which can enhance the system capacity of 2-D OCDMA system. |
