Aiming at the two hop relay's MIMO(Multiple Input Multiple Output) transmission, this paper studied the two hops relay MIMO receiving model which is applicable to these situations: different data stream on the different antenna in the transmitter, different noise power in the transmit channel and SSD(Soft Sphere Decode) in the receiver; And developed a receiving method of the relay link signal and the direct link signal in this model, which is for the purpose of maximum SNR(Signal to Noise Ratio).The BER curves of relay user under different receiving schemes are obtained through simulation.The conclusions are that the developed receiving method is superior to the selective diversity combination algorithm, and it has a considerable robustness to combine signals from different noise power channel.
