A quick Monte Carlo technique for simulating direct-detection optical CDMA communications systems

An exact analysis method for evaluating the performance of direct-detection optical code division multiple access (CDMA) transmission systems is presented. The proposed method is a quick and flexible Monte Carlo technique which substantially reduces the required number of conventional Monte Carlo simulation trials. It is demonstrated that the proposed method can estimate the performance of optical CDMA systems with a high degree of accuracy, warranting its use as a powerful tool for performance analysis, design, and optimization of such systems
