Abstract:
A method comprising the steps of:receiving a signal in an antenna having a plurality of transceiver modules, each transceiver module including an antenna element for receiving a part-signal of the received signal, a controllable phase rotator and a controllable amplifier; controlling a phase rotation of the part-signal using the phase rotator; controlling an amplification of the part-signal using the amplifier; modulating at least one of the phase rotation and the amplification of the part-signal with a predetermined modulation code to correspond to the part-signal; summing all part-signals received in the respective transceiver modules; converting the summed signal from an analog signal to a digital signal; demodulating the converted signal with a demodulation code that is an inverse of the modulation code; and dividing the demodulated signal into at least two separable part-signals which correspond to different reception patterns of the antenna.
