Abstract

This paper presents a low-complexity multiuser MIMO detection algorithm. The MIMO receiver exploits Radial space-Division Multiple Access (RDMA) principle, by paring and scheduling the MIMO multiusers with distinguishable radial space-divisions to the receiver. By exploiting the Channel State Information (CSI) and eigenvalue analysis, the MIMO receiver can selectively deploy the Linear Minimum Mean Square Error (L-MMSE) detection or Successive Interference Cancelation (SIC) for the MIMO multiusers. This reduces the complexity for the multiuser detection, by possibly maintaining the performance. The investigation is provided for the Orthogonal Frequency Division Multiplex (OFDM) system. Throughout this paper, an IEEE 802.16e, Worldwide Interoperability Microwave Access (WiMAX), link level simulator is exploited for the uplink performance evaluation.
