Abstract :
The effect of both shot and thermal noises on the performance of 1D/2D wavelength hopping/time spreading CDMA dynamic noisy 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 dynamic 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 dynamic noisy C2DMA correlation receiver is better than both the dynamic noisy 1D CDMA correlation receiver and the dynamic noisy 2D CDMA correlation receiver. Also a comparison is held between the performance of both idealized and dynamic (1D CDMA, 2D CDMA, and C2DMA) correlation receivers. The comparison reveals in general that the performance of the dynamic C2DMA correlation receiver is better than both the dynamic 1D CDMA correlation receiver and the dynamic 2D CDMA correlation receiver.
