Enhancing Bit Rate using Hybrid Access Method based on NOMA and CDMA for 5G Networks
Author: Yahia Hasan Jazyah
Abstract: Non-orthogonal multiple Access (NOMA) is a transformative wireless communication technique that has gained significant attention for its ability to enhance spectral efficiency and capacity in modern communication systems. Unlike traditional orthogonal multiple access methods, which allocate separate frequency, time, or code resources to users, NOMA controls power domain multiplexing to enable multiple users to share the same time and frequency resources simultaneously. This work provides comprehensive details about NOMA and proposes a hybrid access method that benefits from NOMA and the Code Division Multiple Access (CDMA) to enhance the bit rate in the downlink from Base Station to mobile nodes. Simulation results prove that the proposed technique enhances the bit rate for users even the far ones from the base station.
