According to the first scheme, one antenna which enables gain from a source to a relay channel to reach the maximum is selected from all antennas of a relay for receiving source signals, and afterwards, an antenna which enables gain from the relay to a sink channel to reach the maximum is selected from residual antennas for forwarding source information to the sink. According to the second scheme, transceiving antennas of the relay are directly selected at the same time so that the self-interference channel gain is enabled to be the smallest. According to the third scheme, first of all, one antenna which enables grain from a source to a relay channel to be the maximum is selected from all the antennas of the relay for receiving source signals, and afterwards, one antenna which enables the gain of a self-interference channel to be the smallest is selected from residual antennas for forwarding source information to a sink. According to the invention, a system can adaptively switch the three antenna selection schemes based on calculation of an instantaneous rate, the transmission rate of the system is enabled to the maximized, and the transmission method is applied to some relay networks not convenient for large-scale wired energy supply.
