摘要：A new code structure for spectral amplitude coding optical Code Division Multiple Access (CDMA) system is constructed using �� RD�� code (Random Diagonal) the new code which can be constructed using address level and data level, provides better performance of Bit Error Rate (BER) due to non-existence of Phase induced Intensity Noise (PIIN) at data level, which means that zero cross correlation at data level are always exist, therefore compared with MFH code and MDW code, this new code exist for much wider number of integers, and hence we can choose a code with the desired length more freely. Theoretical analysis result shows that for typical error rate 10-15, it can accommodate 200 users simultaneously. The result indicate that our code is truly performs and applicable to OCDMA network.
