文摘

In this paper an experimental study on the performance of our previously reported optical CDMA co-channel interference reduction is presented, where an end-to-end synchronized CDMA network, implementing a point-to-point fiber-optic link, is modeled in the laboratory test bed. For the first time, the experimental and simulation results on bit-error rates of various prime code families using this laboratory based optical link are presented and compared both in the presence and absence of our previously reported MAI cancellation scheme. Also, to reduce the simulation time during the transmission and verify our results, we have modeled this system in the OptiSystem software. Our experimental results clearly validate all simulations results that we have reported previously.
