Reduction of multiple-access interference for optical CDMA systems

Interference reduction via a cancellation scheme for synchronous optical CDMA systems is discussed. Based on integrating over one bit duration of the received optical signal, the interfering signals can be estimated and cancelled by the desired correlator. Irrespective of high or low load, our proposed method can precisely estimate the interference. Furthermore, thermal noise, APD noise, and interference are included in the analysis. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 1–3, 2001.
