Abstract : The rapid expansion of 5G mobile communication networks, driven by the development of new services and mobile applications, is expected to increase the demand for frequency and bandwidth resources. This growing demand can lead to issues such as reduced speed and increased latency in future cellular networks. Non-Orthogonal Multiple Access (NOMA) is a promising method to address these challenges. NOMA strives to improve user equity, dependability, spectral efficiency, and connectivity, while simultaneously boosting data speeds, adaptability, and decreasing transmission delays. It also improves cell-edge throughput and overall network performance, making it an essential technology for the next generation of mobile networks. several methods have been developed based on the NOMA techniques, however ever increasing demand of mobile communication raised several challenges therefore a robust mechanism is required to deal with the performance related issues in 5G and 6G communication systems. In this work, we focus on these issues and introduced a novel and hybrid mechanism of NOMA where puncturing, interleaving and Turbo coding methods are combined together to develop a robust communication system for both uplink and downlink communication setups. Integrating Turbo codes with interleaving and puncturing in a NOMA 5G system enhances performance by mitigating burst errors, optimizing code rate for bandwidth efficiency, and providing robust error correction. This combination ensures advanced data rates, enhanced spectral efficiency, and improved the quality of service. A thorough experimental analysis is conducted to authenticate the effectiveness of the proposed model. The experimental analysis reveals that the proposed model outperforms existing cooperative, zero forcing (ZF) and maximal ratio combining (MRC) based NOMA systems.
