Embodiment Construction
[0051] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0052] Such as figure 1 As shown, the present invention adopts a kind of general two-way relay communication network that is applicable to two communication source nodes and all relay nodes are equipped with multiple antennas, and the network is defined to be composed of K relay nodes (R 1 , R 2 ,...,R K ) to assist two communication source nodes (T 1 and T 2 ) to complete two-way data communication, each communication source node and relay node are equipped with N antennas and M antennas respectively, abbreviated as (N, M, K) system, defining two communication source nodes T 1 and T 2 There is no direct link between them, each communication node works in half-duplex communication mode, and the information transmission between nodes is completed by Orthogonal Frequency Division Multiplexing (OFDM: Orthogonal Frequency Division Multiplexing). The antenna corresp...
