Abstract A virtual MIMO transmission scheme based on Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) with Block-Space-Time Block Coding (B-STBC)is proposed and a lower complexity detection algorithm for the virtual MIMO system is also presented in this paper. Simulation results show that the proposed scheme can keep the same Peak to Average Power Ratio (PAPR) characteristic as the original DFT-S-OFDM system and reduce the detection threshold of virtual MIMO system, which can improve the transmission reliability in the uplink virtual MIMO system.
