Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes low-latency signal detection methods for overloaded MU-MIMO (Multi-User Multi-Input Multi-Output) OFDM (Orthogonal Frequency Division Multiplexing) and SC-CP (Single Carrier block transmission with Cyclic Prefix) in uplink IoT (Internet of Things) environments where there are a lot of IoT terminals and a base station having the less number of antennas than that of IoT terminals. The proposed method uses non-convex sparse regularizers and group sparsity. Moreover, this paper also proposes an iterative update of parameters in optimization. Simulation results demonstrate the validity of the proposed method.
