Optical CDMA communication systems with multiuser and blind detection

We study the use of multiuser detection and blind detection techniques to improve the performance of optical code division multiple access (OCDMA) systems. First, a new multiuser receiver known as the interference suppression receiver is proposed. Second, we study the use of blind detection by proposing a blind receiver for OCDMA systems. While previous studies on multiuser detection are limited to systems with p-i-n detectors, avalanche photodiode detectors are also included here.
