Abstract: In this paper we consider an optical code division multiple access (OCDMA) indoor wireless communication system using spectral encoding and evaluate its performances in cases of classical OCDMA, dynamic OCDMA and OCDMA with deconvolution. We present an analysis of the receiver movement influence on the indoor wireless communications system performances. As the receiver moves increasingly away from transmitter the amount of power received in that place will be getting smaller and system performances are affected. Knowledge of the impulse response in different positions in the room allows calculation of the amount by which power is lower at that point. We showed that increasing the power received in that place with the necessary amount, system performance are maintained at the same values, even if the receiver is moving away from transmitter. The bit error rate (BER) was estimated by means of simulations for several scenarios. The simulation results confirm the fact !
that using deconvolution in OCDMA systems, the multipath interference is reduced and the BER performances are significantly improved for diffuse configuration, as compared to the case without deconvolution.
