Simulation study of different code system division multiple access (DCSDMA) for optical communication

In this paper, we propose a novel structure using different code system division multiple access (DCSDMA) for an optical communication system and a design algorithm to increase the system capacity. This DCSDMA system can transmit two kinds of code systems (for example, the prime code of 7 and 3, respectively). This multicode architecture can improve the theoretical system capacity from P-7(2) to P-7(2) + 5 * p(3)(2). In this paper, we propose an optimal design method lo find the simultaneous capacity X% * 7(2) + Y% * 5 * 3(2). X% and Y% are the successful percentages determined by the simulation results.
