Abstract
A method of joint communication and sensing of a target obstacle (object or human) is disclosed. The method comprises deploying a joint communication and sensing transceiver, comprising a transmitter (TX) having at least two transmitting antennas and a receiver (RX) having at least one receiving antenna; transmitting at least two radio frequency (RF) signals carrying data to a communication receiver by the at least two transmitting antennas; and receiving at least one reflected radio frequency (RF) signal reflected by the target obstacle by the at least one receiving antenna; wherein the at least two RF signals transmitted by the at least two transmitting antennas are applied with cyclic shift diversity; and wherein the at least two RF signals transmitted by the at least two transmitting antennas contain TX-varying phase rotations.
