A DETECTOR FOR OPTICAL CODE-DIVISION MULTIPLE-ACCESS SYSTEM WITH CO-CHANNEL INTERFERENCE CANCELLATION

Michal Poľaško

   Code-division multiple-access (CDMA) is a multiplexing scheme which is particularly attractive for fiber-optic communication systems where a broad bandwidth is available. This paper considers the problem of demodulation in optical synchronous CDMA system. Simulation results of a multiuser detector with co-channel interference are presented. It is shown that such a detector can provide lower bit error probability than the conventional correlation detector when exact knowledge of interfering users is available.
