Abstract |
A new code structure for Spectral-Amplitude Coding Optical Code Division Multiple Access (OCDMA) system with zero cross-correlation is been proposed in this paper. In contrary to the existing code, Zero Cross-correlation (ZCC) code provides much better performance of Bit Error Rate (BER) due to non-existence of Phase Induced Intensity (PIIN) noise. The newly proposed code can adapt to any variable number of weight and user without any constraint by using transformation and mapping technique respectively. Thus, we demonstrate in theoretically to compare the performance of ZCC code with the existing codes such as Hadamard, Modified Frequency Hopping (MFH) and Modified Double-Weight (MDW) codes. For typical error rate of optical communication system, 10-9, it can accommodate 84 users simultaneously. The results indicate that our code is truly performs better than obtained OCDMA codes and applicable to OCDMA network. |
