In the field of optical communications, designing capacity-achieving codes is crucial for high-speed, and high reliability data transmission for multiple users. This thesis presents a practical coding scheme tailored specifically for Optical Intensity Multiple Access Channels (OIMACs). The innovative contribution is the binary decomposition of the OIMAC into a collection of N bit-pipes, resulting in the formation of the Vector Binary Multiple Access Channel (VBMAC). The research outlines five distinct coding schemes for the VBMAC, detailing the encoding and decoding processes, along with the
achievable rates for each scheme. Performance evaluations of these schemes are presented while adhering to practical constraints. Compared to capacity and bounds, the devised coding schemes show promising results, which closely approximates capacity at moderate and high Signal-to-Noise Ratio (SNR) levels. This work signifies a pivotal step towards improving the efficiency and reliability of multiple access channel transmissions, meeting the increasing demand for robust and high-capacity communication systems.
