Abstract

The present invention provides a method of selecting antennas, devices and video glasses. The method includes: in a different time period, a first device receives a sounding signal sent by a second device on different channel groups, where each channel in each channel group is an antenna of the second device and the The first device performs channel estimation on each channel according to the sounding signal, and determines a channel parameter of each channel; and the first device determines, according to the channel parameter from The antenna of the second device and the antenna of the first device. Receiving sounding signals by time division and estimating channel parameters, selecting a working antenna according to these channel parameters can simplify the circuit of the transceiver of the communication device, save power resources and improve communication quality.
