Performance Analysis of Cooperative Non-Orthogonal Multiple Access System Using Detectors

One method that shows promise for improving spectral efficiency in wireless communication systems is cooperative non-orthogonal multiple access, or NOMA. The performance analysis of the cooperative NOMA system with the greedy detector and maximum likelihood detector (MLD) is presented in this paper. Through the use of several users' power to transport data non-orthogonally, the cooperative technique improves resource use. By maximizing user allocation and symbol decoding, the MLD improves detection accuracy. Using theoretical derivations and simulations, we examine the system's performance and emphasize its capacity and reliability advantages. Our findings show that the suggested cooperative NOMA system with greedy detectors and MLD performs better than other cooperative approaches and conventional NOMA, which makes it an attractive option for wireless networks of the future generation.
