摘要

分析了在接收端采用直接检测(DD)技术的频谱幅度编码-光码分多址(SAC-OCDMA)系统中对角特征值统一(DEU)码的行为。具有理想相位互相关的DEU码族是基于Jordan块矩阵的。DD技术在检测过程中对每个用户使用不重叠的波长。DD技术消除了相位诱导强度噪声,降低了接收机结构的复杂性(接收机设计中元件数量较少),从而降低了系统成本。利用OptiSystem 13 (OptiWave)和Matlab分别进行了仿真和数值计算。

Analysis of Diagonal Eigenvalue Unity (DEU) code for Spectral Amplitude Coding OCDMA systems using Direct Detection technique
The behaviour of Diagonal Eigenvalue Unity (DEU) code for Spectral Amplitude Coding - Optical Code Division Multiple Access (SAC-OCDMA) system using a Direct Detection (DD) technique at receiver is analysed. DEU code families with ideal inphase Cross Correlation are based on Jordan block matrix. DD technique uses non-overlapping wavelengths for each user in detection process. DD technique eliminates Phase-Induced Intensity Noise and reduces the complexity of receiver structure (less number of components in receiver design) thereby reducing system cost. Simulation and numerical results are obtained using OptiSystem 13 (OptiWave) and Matlab respectively.
