| Abstract: | A relay transmission scheme based on virtual MIMO with block space time block coding is proposed for LTE TDD uplink 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 improve the transmission reliability for the mobile equipments located in cell-edge and blind spots, the decrease of spectral efficiency in conventional relay transmission scheme can also be avoided. |
