WebDec 4, 2016 · In this paper, the performance comparison between NOMA and conventional OMA systems is investigated, from an optimization point of view. Firstly, by using 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 .
WebSecond, we show that NOMA incurs a severe multiplexing gain loss despite an increased receiver complexity due to an inefficient use of SIC receivers. Third, we emphasize that much of the merits of NOMA are due to the constant comparison to OMA instead of comparing it to MU–LP and RS baselines. WebJun 16, 2024 · Figure 4 shows the comparison of the throughput performance between the proposed NOMA-based system and the benchmark system based on OMA. It can be seen that with the increase of \(\beta \), the trend of the throughput curve of OMA-based system is the same as the one of NOMA-based system. Furthermore, the introduction of NOMA …
WebApr 13, 2024 · In this paper, we propose a rate-splitting-based generalized multiple access (GMA) scheme for band-limited multi-user visible light communication (VLC) systems. By splitting and transmitting the input data of each user in a joint orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) manner, the proposed rate-splitting …
