WIRELESS COMMUNICATION CIRCUIT SUPPORTING ANTENNA DIVERSITY |
摘要 |
A wireless communication circuit for a wireless communication device having a plurality of antennas is disclosed. The wireless communication circuit includes: a transceiver for receiving and transmitting network packets; a control circuit for controlling the switching circuit to switch the transceiver among the antennas so that the transceiver receives the preamble of a first network packet; and a receiving signal strength detector for detecting the receiving signal strength value of respective antennas in respective receiving periods during the reception of the preamble conducted by the transceiver. If the receiving signal strength value of each antenna is less than a predetermined threshold, the control circuit selects an antenna with the maximum receiving strength value as a target antenna and controls the switching circuit to couple the transceiver to the selected target antenna so that the transceiver receives the rest of the first network packet through the target antenna.
