Abstract: Optical Code Division Multiple Access (OCDMA) is a technology used in optical communication systems to multiplex many signals onto a single optic line. Each signal in OCDMA is allocated a unique code, which the receiver decodes using a matching filter. In this paper, a novel 4 Dimensional Spatial-Wavelength-Zero Cross Correlation (SWZCC) encoding scheme for high-capacity optical communication system has been proposed. The system incorporates advanced multiplexing across 4D technique is a combination of polarization, spectral, temporal, and spatial to enhance data transmission efficiency and robustness. Primary light signals are generated by optical sources and encoded through 4D-SWZCC modulation with non-return-to-zero (NRZ) signal for transmission via Line-of-Sight (LOS) optical channel. The receiver converts the optical signal into electrical data by splitting it and decoding it with a photo detector. By using polarization multiplexing as well as wavelength division multiplexing (WDM), the proposed system minimizes crosstalk and signal degradation while maximizing spectral efficiency. Optical communication solutions for next-generation networks are demonstrated by this system by illustrating high performance and scalability. The proposed model outperforms the existing techniques, such as NOMA-VLC, WMZCC, RSMA-VLC respectively. Proposed method achieves a BER of 1.0%, which is 71.4% lower than NOMA-VLC of 3.5%, 60% lower than WMZCC of 2.5%, and 50% lower than RSMA-VLC of 2.0%. [ABSTRACT FROM AUTHOR]
