Abstract:
1. A computer implemented method for selecting antennas in a multiple-input, multiple-output wireless local area network including a plurality of stations, each station includes a set of antennas, comprising the steps of: sending a number of sounding packets that are to be sent for antenna selection training, from a station to perform the antenna selection training by receiving the sounding packets, to a station to transmit the sounding packets; transmitting multiple consecutively transmitted sounding packets, according to the number, by the station transmitting the sounding packets; receiving the multiple consecutively transmitted sounding packets in the station to perform the antenna section training, wherein each sounding packet corresponding to a different subset of the set of antennas, and where the number of consecutive packets is predetermined; estimating a channel matrix from the multiple consecutively transmitted sounding packets; and selecting a subset of antennas according to the channel matrix.
