| Abstract(in English) | Interleave division multiple access (IDMA) is a Non-Orthogonal Multiple Access (NOMA) technique regarded as an enabling technology for next generation wireless systems. IDMA can improve the system efficiency by supporting multiple access for a large number of stations. In this paper, we employ higher order QAM modulation up to 256-QAM for high spectral efficiency transmission. We show our receiver architecture which uses a soft demapper that significantly decreases the receiver detection complexity. Our proposed system is much more suited in modern multi-mode transceivers aside from the fact that it has a lower complexity. |
