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.

A transceiver for use in a radio communication system wherein said transceiver is one of a plurality of transceivers and communicates with at least an other of said transceivers, said one transceiver being remote from said other transceiver; said one transceiver comprising: a plurality of receiving antennas for producing separate received antenna signals from radio signals received from said other transceiver; detecting means coupled to the receiving antennas for detecting a time delay between the received antenna signals; transmitting means including a plurality of transmitting antennas for transmitting radio signals which are received at said other transceiver; and means coupled to said transmitting means and further being responsive to an output of said time delay detecting means for producing a time delay between the transmitted radio signals which substantially matches the detected time delay between the received antenna signals.
