Abstract

A novel multiple user interference (MUI) cancellation technique is introduced with a reference signal which is data-free from the intended signal. It also simplifies the receiver architecture in synchronous M-ary wavelength or frequency shift keying (FSK) OCDMA. In the analysis, the system upper-bounded bit-error rate (BER) is derived taking into account the Poisson effect on the I/O characteristics of the photo-detectors (PD). It is found that the capacity of this system also increases by employing the proposed MUI canceller. In contrast to wavelength-division multiplexing (WDM), fewer wavelengths are needed as a result of M-ary source coding. (c) 2008 Wiley Periodicals, Inc.
