WebThe non-orthogonal multiple access (NOMA) technique has evolved as one of the potential technologies for efficient utilization of resources in wireless communication systems [1,2,3].Unlike the orthogonal multiple-access (OMA) scheme, larger number of users can be connected to a wireless network concurrently in a NOMA scenario [].Furthermore, the … WebJul 16, 2024 · The basic benefits of a NOMA system over an OMA are defined. One of the main benefits of using NOMA scheme is that two users can concurrently use 1 Hz BW. However, that is not the case in the existing OMA technique was user 1 uses α Hz of BW. The remaining (1-aa) Hz shall be allocated to user 2 .
