The system performance of 2-D wavelength hopping/time spreading CDMA system
s is found to be limited by the occurrence of the beat noise between the co
mponents of the signal and the multiple user interference. The variance of
the noise is determined and the probability of error is calculated for a ge
neral system employing asymmetric prime-hop sequences. Comparison with an i
dealized system neglecting the beat noise reveals that the system performan
ce is seriously affected by the beat noise.
