For the multi-relay two-hop multiple input multiple output system, a kind of relay transmission scheme and interference alignment algorithm is put forward. Firstly, the transmitting beamforming is adopted by the scheme between sources and relays to utilize the spectrum efficiently. Then the relays forward the signals using interference alignment technology. Finally, the interference is eliminated at the ends with a low computation interference eliminate algorithm. Simulations show that the transmission scheme can achieve better system capacity and energy efficiency.
