Title : Combining OAM beams with SAC-OCDMA in free space optics communications for capacity enhancement

Abstract:

Four orbital angular momentum (OAM) beams, each carrying three independent channels with a 10 Gbps data rate, are combined with the spectral amplitude coded (SAC)-optical code division multiplexing access (OCDMA) technique, forming a new system. Enhanced double weight (EDW) codes are employed for the SAC-OCDMA system. The system is applied to free space optics communications and its performance is studied under different weather conditions: clear air, rain, haze, and fog. The results are obtained through simulating the proposed model using Optisystem software. The obtained results reveal successful data transmission under various weather scenarios with an overall capacity of 120 Gbps.
