Abstract
A wireless communication device includes a number of radio-frequency (RF) antennas and one or more radio circuits. Each radio circuit includes a receive (RX) chain to process RX signals and a transmit (TX) chain to process TX signals. An RF switch network couples at least one RF antenna to at least one radio circuit. A baseband processor controls a configuration of the RF switch network. The baseband processor determines a plurality of parameters and controls the RF switch network based on at least one of the parameters. The parameters are determined during a training interval including at least an inter-frame space (IFS). The configuration of the RF switch network is based on the determined parameters and is employed for selection of an antenna to improve a link performance when used for communication of a next packet following the IFS.
