Abstract
A wireless communication apparatus includes a channel estimation circuit, a beamforming control circuit, and a transmit (TX) circuit. The channel estimation circuit estimates a channel between the wireless communication apparatus and another wireless communication apparatus during at least one first time slot. The beamforming control circuit determines beamforming coefficients according to the estimated channel. The TX circuit applies the beamforming coefficients to transmission of an output data during at least one second time slot later than the at least one first time slot. During the at least one second time slot, the output data is transmitted to another wireless communication apparatus via multiple antennae. The wireless communication apparatus performs communications according to a normal frequency hopping sequence in compliance with a communication specification.
