Impact of different transceiver design on the performance of SAC-OCDMA systems
Multiple-access interference (MAI) and phase-induced intensity noise (PIIN) are the principal limitations for the performance of spectral-amplitude-coding optical codedivision multiple-access (SAC-OCDMA) systems. Focusing on increasing the performance and reducing the bit-error rate (BER), the ideal transceiver design should be accentuated. In this paper, we studied the effect of the different combination of codes, detection techniques, and the usage of single and multiple light emitting diodes (LEDs) in SAC-OCDMA system to highlight the main point that affect the most in reducing the BER as well as increasing the performance. We simulate the system performance of direct detection, AND subtraction detection, as well as modified-AND subtraction detection techniques with enhanced double weight (EDW) and modified double weight (MDW) codes via OptiSystem software. Simulation results show that the detection techniques significantly enrich the performance compared to the usage of diverse codes. Although the multiples LEDs give better performance than single LED in SAC-OCDMA system, the single LED still able to provide a good performance with less costly design than multiples LEDs.
