Abstract
A method of joint communication and sensing of a target obstacle includes deploying an integrated sensing and communication (ISAC) node having an ISAC transmitter having M transmitting antenna(s) and a radar receiver having L receiving antenna(s), wherein the M and L are integers; transmitting radio frequency (RF) signals carrying data to a communication receiver by the M transmitting antenna(s) of the ISAC transmitter; receiving radio frequency (RF) signals reflected by the target obstacle by the L receiving antenna(s); and obtaining a sounding result based on the reflected radio frequency (RF) signals; wherein the RF signals are applied with cyclic shift diversity; and wherein the RF signals contain precoders which are selected by aligning a range of communication direction linked to a communication channel between the ISAC node and the communication receiver with minimal capacity loss based on the sounding result.
