The information processing method of two-way relaying system Mimo

The present invention discloses a method of MIMO two-way relaying information processing system of the wireless communications art, the steps of: transmitting a training sequence of the source node to the relay, the relay performs channel estimation process to obtain between the source node and the relay 1 and the estimated channel estimation error variance; source relay node to transmit a training sequence 2, the relay performs channel estimation process, and to obtain an estimated channel estimation error variance between the source node and the relay 2; relaying obtained based on the estimated channel, applying an iterative algorithm and the reception processing matrix matrix relay node; the source node, respectively, a transmit signal to the relay; relay linear signal processing, and forwarded to the two destination nodes; two destination node from the interference cancellation process; node of the processed signal from the interference cancellation detection process, to complete the exchange of information between the two source nodes. The present invention contemplates a channel estimation error, can effectively improve the mean square error and the bit error rate performance of the system.
