Abstract:

We consider a multicarrier (MC) single-cell mobile communication system with In-band full duplex (IBFD) capable base station (BS) and half duplex (HD) mobile nodes. The BS employs non-orthogonal multiple access (NOMA) technique for both uplink (UL) and downlink (DL) communication. We assume superposition of more than two users can be done in any given direction using NOMA. We maximize sum rate subject to total power constraints at the BS and at the UL users. We propose a modification to the particle swarm optimization (PSO) algorithm to reduce computational complexity. We compare the performance of our modified PSO with the block coordinated descent (BCD) algorithm proposed in baseline scheme. Our simulation results show significant improvement in terms of sum rate when compared to baseline algorithm. We also compare the performance with half duplex BS employing NOMA in a given direction.
