Abstract
In this paper, we have studied the probability of error of optical code
division multiple access (OCDMA) system using 2-D optical codes, namely
prime hop and hybrid codes with a probability distribution approach. In
order to increase the OCDMA system performance and increase the number of
simultaneous users in the system, we have investigated the system when two
different receivers are employed, namely, OCDMA serial interference
cancellation (SIC) receivers and OCDMA correlation conventional receiver
(CCR). Comparison in terms of OCDMA system's performance between these two
receivers has been reported. In order to obtain the optimum OCDMA system's
performance, we have studied several optical SIC receiver structures.
Optimum choice of the number of stages in the SIC receiver and the threshold
value on each stage has been reported.
