Title : Multi-stage Receiver based on Tabu Search (TS) Algorithm for FS-NOMA Systems 
Authors : Insik Jung, Jinkyo Jeong, and Daesik Hong 
Conference : ICEIC 
Abstract : This paper proposes a new scheme for multiuser receiver for full-spreading non-orthogonal multiple access (FS-NOMA) systems. We exploit the tabu-search (TS) algorithm which is sort of meta-heuristic algorithms. However, direct application of TS algorithm causes performance degradation because of the low quality initial solution. To overcome this, we propose a multi-stage receiver based on QR factorization technique. Simulation results demonstrate that the proposed receiver outperforms conventional FSNOMA receivers and the complexity of it is reasonable.
