Performance Comparison of Different SAC-OCDMA-FSO Detection Techniques in Presence of Atmospheric Losses

The development of many high bit-rate multimedia applications has emphasized the demand for service differentiation or prioritization techniques to ensure end-user quality-of-service (QoS) necessities. This paper focuses on utilizing different detection schemes in spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems to support 'triple-play' services (voice, video, and data) with diverse QoS requirements. The system is simulated with enhanced double weight (EDW) code for complementary subtraction detection (CSD), modified-AND detection, as well as single photodiode detection (SPD) technique via OptiSystem software.
