Study Summary: As we transition from 5G to 6G, the demand for massive connectivity and high spectral efficiency is skyrocketing. In this study, we proposed a hybrid multiple access technique that integrates Non-Orthogonal Multiple Access (NOMA) with Interleave-Division Multiple Access (IDMA). This combination leverages the power domain of NOMA and the interleaving capabilities of IDMA to serve multiple users simultaneously on the same frequency resource. Our simulation results demonstrate that this NOMA-Integrated IDMA scheme significantly outperforms traditional OMA schemes in terms of Bit Error Rate (BER) and user capacity.

Behind the Research: The future of the internet isn't just about faster phones; it's about connecting billions of IoT devices seamlessly. Traditional access methods are hitting a wall—they simply can't handle the traffic density required for smart cities and industrial automation. We realized that no single existing method was the "silver bullet." By fusing NOMA's ability to stack users with IDMA's robustness against interference, we created a system that doesn't just manage congestion but thrives on it. This work is a glimpse into the architectural backbone of the next generation of wireless networks.
