Abstract
In this paper, a pulse-shift technique, which divides every time slot (or chip) into equal-width subchips, is used to model the effect of fiber temperature fluctuations in incoherent (asynchronous) optical code-division multiple-access (O-CDMA) systems. With the advances in all-optical thresholding technology, power detection of ultrashort optical pulses is possible. This paper also formulates a new pulse-power-detection model for incoherent O-CDMA and applies it to the analysis of the pulse-shift technique. Numerical studies and computer simulations are presented to validate the new analytical model. Our study shows that the pulse-power model results in better performance than the conventional pulse-energy model in incoherent O-CDMA.
