Time-spreading wavelength-hopping 2D-OCDMA system with optical hard limiter

摘要

The performance of time-spreading wavelength-hopping two-dimensional optical division multiple access (2D-OCDMA) system with optical hard limiter was analyzed firstly. Prime/OOC codes are employed as address codes. By dividing other codes into three groups according to the sum of shift cross-correlations and analyzing the probability distribution of the interference patterns, the bit error rate (BER) of the system was obtained.
