The system performance of 2-D wavelength hopping/time spreading CDMA systems is found to be limited by the occurrence of the beat noise between the components of the signal and the multiple user interference. The variance of the noise is determined and the probability of error is calculated for a general system employing asymmetric prime-hop sequences. A comparison with an idealized system neglecting the beat noise reveals that the system performance is seriously affected by the beat noise.
