Abstract

Several channel interference cancelation techniques have been proposed in different journals aiming at lowering to asymptotic bit error floors in optical OCDMA systems. These interference cancellation techniques are classified into two groups. One is based on the use of properties of sequence codes and another is based on the use of non linear elements in OCDMA systems. Optical hard-limiter is such a non-linear optical device which is used to reduce the MAI to some extent in OCDMA systems. Purpose of this paper is to investigate the impact of channel interference cancellation techniques when used individually or together on Incoherent Optical CDMA systems.
