Abstract

Performance of asynchronous phase-encoded OCDMA system is evaluated on the condition that receiver noise and the impact of fiber channel are neglected. Phase-encoded optical signal (pseudo random optical signal with low intensity) is analyzed in the view of stationary random process. The pseudo random optical signal with low intensity is seen as a sample function of a certain stationary random process which is ergodic in strict sense. The analysis results reveal that the variance of the corresponding random process is only inversely proportional to the code length while the root-mean-square width of the phase-encoded optical signal is proportional to the width of initial optical pulse and the code length F. The numerical results demonstrate that the better system performance can be achieved in case of larger code length and shorter initial optical pulse.
