Method of selecting antennas, devices and video glasses

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.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of antennas, and in particular, to a method, device and video glasses for selecting an antenna.

AI Technical Summary

Problems solved by technology

[0008] However, in this solution, each antenna is connected to a radio frequency circuit, and the cost and power consumption of the communication transceiver are high.

Also, usually some receiving antennas receive much lower signal strength than other receiving antennas, and this part of receiving antennas does not help the communication quality.

In addition, regardless of the situation of each transmitting antenna, the power is evenly distributed to all transmitting antennas, which may cause waste of power resources
