Numerical simulation of data transmission in 2D W/T optical CDMA system with optical hard-limiters

Abstract

The proposed numerical model of 2D W/T optical CDMA system with optical hard-limiters is presented in this paper. The decoder input and output signal, average signal to interference difference and bit error probability as a function of active user number and weight of codeword for the different topologies of the decoder have been simulated. The influence of non-ideal properties of the used optical hard-limiters and different topologies of the decoder upon average signal to interference difference and bit error probability in system are studied.
