Classification: CPC H | IPC H

Claim 6:
7. The method according to claim 1, wherein before the switching a current transmit antenna based on the spectrum effectiveness of the at least two antennas, the method further comprises:
detecting a downlink received energy of the at least two antennas and that is within a downlink estimated time;
determining whether an absolute value of a second difference is greater than or equal to a preset energy threshold, wherein the second difference is a difference between a downlink received energy of an antenna with a highest downlink received energy in the at least two antennas and a downlink received energy of an antenna with a lowest downlink received energy in the at least two antennas; and
the switching a current transmit antenna based on the spectrum effectiveness of the at least two antennas comprises:
when the absolute value of the second difference is greater than or equal to the preset energy threshold, determining whether a spectrum effectiveness of the current transmit antenna is less than a preset switching threshold; and
when the spectrum effectiveness of the current transmit antenna is less than the switching threshold, switching the current transmit antenna to an antenna with a highest spectrum effectiveness in the at least two antennas.
