Abstract:
1. A communications apparatus, comprising: a plurality of antennas, arranged to receive downlink signals and transmit uplink signals; a transceiver module, arranged to receive the downlink signals from the antennas and pass the uplink signals to an antenna selection device; the antenna selection device, coupled between the antennas and the transceiver module, arranged to receive the uplink signals to be transmitted from the transceiver module and dynamically pass the uplink signals to one of the antennas according to an antenna selection signal; and a processor, arranged to receive the downlink signals from the transceiver module, calculate short-term signal qualities of the downlink signals received in an antenna switching period and generate the antenna selection signal according to the short-term signal qualities, wherein the processor calculates the short-term signal qualities and generates the antenna selection signal during the antenna switching period.
