<p>A transmitter/receiver device communicates with a remote transmitter/receiver device. The remote transmitter/receiver device sends two transmit signals from transmit antennas positioned at different spatial positions. A receiving quality evaluator evaluates a receiving quality of the signal at the transmitter/receiver, and the feedback generator generates a feedback signal for the remote transmitter/receiver, when the receiving quality is below a threshold. The feedback signal is received by the remote transmitter/receiver, which generates a phase control signal controlling a phase encoder to change a phase relationship between the transmit signals. Alternatively, the receiving quality for a signal from the transmitter/receiver is determined by the remote transmitter/receiver itself so that a feedback signal is not required.</p> |
