The invention discloses a full-duplex energy collection relay transmission method based on a self-interference minimization criterion. The method comprises the following steps: acquiring information received by a destination end and a corresponding first signal-to-noise ratio; selecting a receiving antenna and a transmitting antenna of the relay; acquiring a signal received by a relay in the first time slot alpha T; acquiring a signal received by the relay when the source information is transmitted through the relay in a second time slot (1-[alpha]) T; in a second time slot (1-[alpha]) T, when the source information is transmitted through the relay, obtaining information received by the destination end and a corresponding second signal-to-noise ratio; the destination end adopting a maximum ratio merging technology to merge information from a relay and a source, and summing the first signal-to-noise ratio and the second signal-to-noise ratio to obtain a received signal-to-noise ratio of the destination end; an
