Analysis of the effect of shot and thermal noises on the performance of static OC²DMA correlation receivers using Fiber Bragg Grating

摘要

The effect of both shot and thermal noises on the performance of 1D/2D wavelength hopping/time spreading CDMA static noisy system is analyzed. The probability of error is calculated for general systems employing asymmetric prime-hop codes (APHCs). A comparison is held between the performance of static 1D CDMA, 2D CDMA, and C2DMA correlation receivers under the effect of both shot and thermal noises. The analysis reveals that the performance of the static noisy C2DMA correlation receiver is better than both the static noisy 1D CDMA correlation receiver and the static noisy 2D CDMA correlation receiver. Also a comparison is held between the performance of both idealized and noisy static (1D CDMA, 2D CDMA, and C2DMA) correlation receivers. The comparison reveals in general that the performance of the static C2DMA correlation receiver is better than both the static 1D CDMA correlation receiver and the static 2D CDMA correlation receiver.
