Abstract:Non-orthogonal multiple access (NOMA)-based cooperative relaying system (CRS) has emerged as a solution to the spectral inefficiency problem of the conventional CRS thanks to the NOMA integration. Thus, as a subset of the NOMA-CRS, the NOMA-based diamond relaying network (NOMA-DRN) also provides a performance gain in terms of throughput. However, the NOMA-DRN has a poor error performance due to the second phase (uplink), indeed, it has an error floor regardless of the transmit power, power allocation and chann… Show more
