Ever increasing demand for high-capacity and low-bit-error-rate optical communication networks has become imperative with the pervasive use of data-intensive applications such as social networking, cloud computing, and high-definition digital services. This research paper introduces a novel approach to enhance optical communication performance by a Modified Orthogonal Frequency Division Multiplexing system with Relational Reconfigurable LDPC Decoding. This system integrates Asymmetric Clipped Optical Orthogonal Frequency Division Multiplexing (ACO-OFDM) and DC-biased Optical Orthogonal Frequency Division Multiplexing (DCO-OFDM) with Multi-Layer Modulation (MLM) to fulfil the high channel capacity requirements of next-generation access networks. A key feature of this work is the development of a non-binary Relational Reconfigurable Low-Density Parity Check decoding method to effectively identify and correct errors. The proposed system is rigorously evaluated and compared to existing techniques, demonstrating remarkable improvements in terms of bit error rate (BER), spectral efficiency, and multipath distortion tolerance. The results of this work reveal that the Modified ADCO-OFDM system with Relational Reconfigurable LDPC Decoding presents a promising solution to achieve a low-bit-error-rate, cost-effective optical communication network.
