Performance Comparison of RSMA and IDMA for NOMA Application

Abstract

As we know that communication is must among humans and it also have upgradation in technology for better effective communication. For that human will must ensure that it has been best multiple access scheme as performance-wise and easy to access at large scale. At present, out of all multiple access the best multiple access is NOMA which is very beneficial for 5G and beyond communication network. And for the applications of NOMA, which require best technique to access the NOMA applications. And today onwards IDMA and RSMA is more successful techniques. It has been noticed that for differentiate the multiple users IDMA plays very important role because it has the property of interleaving or scrambling. But trade off is complexity at receiver side occur.  Hence, to reduce the complexity of receiver in IDMA the another technique RSMA introduced. In which it has find that RSMA gain good efficient performance with simpler architecture due to which it helps to minimize performance delay. In this paper, our comparison has been proved that RSMA gives quite good performance with low-complexity architecture.
