Multi-antenna receiver with common time synchronisation for the various receiver channels

摘要

A receiver of a signal constructed in the form of successive frames, comprising a plurality of antennas, a signal receiving chain associated with each antenna, and a power amplifier on each receive channel to which is applied a gain setpoint provided by a gain control unit (AGC0, AGC1), characterized in that it comprises an antenna selection unit (SA) configured to select one of the plurality of antennas, and a unit time synchronization (ST) configured to determine the start and end times of frames in the signal received by the selected antenna, the antenna selection unit (SA) being configured to evaluate the gain setpoint of each of the reception channels and for eliminating from said selection the antennas associated with a reception channel with a non-permanent gain gain command
