ABSTRACT:
A transceiver for use in a radio transmission system has a plurality of receiving antennas and a plurality of transmitting antennas. The time delays between received antenna signals produced by a radio signal transmitted from another transceiver in the system are detected. For transmission, the time delays between the transmitted antenna signals are adjusted to correspond to the detected time delays between the received antenna signals. By antenna sharing, each may actually serve for both transmission and reception. Since the delayed transmitted signals will arrive simultaneously at the other transceiver they will superpose on each other, thus achieving a significant improvement in received signal strength at such transceiver.
