Implementation of IDMA System with Multiple Access Channel and non-Gaussian Noise

Abstract

Non-orthogonal multiple access (NOMA) has been proposed as one of the efficient techniques to build essential components of the modern mobile networks. The expected advance of NOMA system is the improvement of possible spectrum when compared with the classical orthogonal multiple access (OMA). Interleave division multiple access (IDMA) is a very low code rate NOMA scheme which has been used as a new version of the third generation (3G) wideband CDMA system in recent years. Moreover, it can be a promised candidate for potential use in the fifth generation (5G) because it explores the possibility to share frequency, time resources and spreading codes. In this paper, we evaluate the effect of non-Gaussian noise to the IDMA system with multiple access channel. In particular, the bit error rate (BER) will be used to compare the performance of different simulation scenarios.
