Embodiment Construction
[0016] Such as figure 1 As shown, a non-orthogonal based uplink relay full-duplex transmission mechanism model, the specific implementation steps are as follows:
[0017] Uplink user 1 and user 2 allocate transmission power β by using the self-generated channel to the relay station 1 P t with beta 2 P t , where β 1 +β 2 = 1, β 1 >β 2 . It is assumed that neither of the two users can directly communicate with the base station, thus, cooperative transmission of the relay station is required. Without loss of generality, it is also assumed that user 1 is closer to the relay station than user 2 is to the relay station.
[0018] The relay station is a full-duplex antenna, so full-duplex transmission can be implemented. The two-user signals from the uplink received by the receiving end of the full-duplex antenna can be expressed as:
[0019]
[0020] where h 1r [n], h 2r [n] with h r [n] represent user 1 and relay, user 2 and relay and self-interference channel coeff...
