Abstract

We present the bit-error-rate (BER) analysis of an ultrashort light pulse code-division multiple access (CDMA) communication system, which employs a practical nonlinear detector. The system considered here assumes a CDMA network, in which M user stations are connected via a star coupler and a common fiber channel. The transmitter at each station consists of a mode locked femtosecond fiber laser at 1550 nm whose ultrashort pulses are encoded by a spectral phase encoder and uses an on- off-keying scheme. The receiver consists of a decoder, a nonlinear detector, and an integrate and dump data circuit. In this work, we develop an efficient Monte Carlo simulation using importance sampling scheme to estimate the error probabilities of the system in addition to the analytical technique. The simulation results are found to be in good agreement with the analytical results.
