US 7,983,645 B2 · Method and device for radio reception using a plurality of antennas

Abstract

The invention relates to a method for radio reception using a plurality of antennas and to a receiver for radio transmission using a plurality of antennas. In a receiver for radio transmission with multiple antennas of the invention, 3 antennas are connected to the input ports of a device for transmission which transmits the electrical signals stemming from the 3 antennas to the input terminals of a multiple-input-port and multiple-output-port amplifier having 3 input ports and 3 output ports. Each output port of the multiple-input-port and multiple-output-port amplifier is connected to the input of an analog processing and conversion circuit which outputs digital signals. The output of each analog processing and conversion circuit is connected to an input of a multiple-input signal processing device, whose output is connected to the destination.
