Performance Analysis of A Fiber Optic CDMA LAN Using A Time Domain System Model

摘要

A time domain system model is developed for studying the performance of a FO-CDMA LAN (i) with non-ideal network parameters and (ii) in the presence of multi-user interference (MUI). We examine the effect of chirping in a laser diode on its spectral response. Effects of changes in laser device parameters on its output are studied. Error performance of the complete system, including non-idenlities of laser source, optical fiber channel and the APD detector is studied using our time domain simulation model, in the presence of MUI. The effect of having two hard-limiters on the system performance is studied. Our simulation result is verified with the help of an analytical model.
