Abstract

Phase induced intensity noise (PIIN) is one of the noises involved in incoherent OCDMA systems. In this paper, we analyze the influence of PIIN on the system performance of new proposed 2-D Hybrid FCC- MDW code. The numerical result indicates PIIN is a major factor of the performance depreciation as compared to the shot noise and thermal noise. The comparison results with thermal noise and shot noise reveals that the system performance is seriously affected by PIIN and other two noises can be neglected. Moreover, the numerical analysis demonstrates the PIIN value of the proposed code is lower than the 2-D Perfect Difference (PD) code and 2-D Modified Double Weight (MDW) code. Consequently, the performance of the 2-D Hybrid FCC- MDW OCDMA system is better than other two codes. The results presented here may facilitate improvements in the understanding to develop a new incoherent OCDMA code.
