Precoding weights are computed in real time to steer deep nulls toward neighboring sensing nodes, letting high-power data beams and sensitive radar receivers share spectrum without desensitizing each other.
Before transmitting a high-power data beam, the array solves for Zero-Forcing precoding weights that place a deep attenuation notch directly over the receive antennas of neighboring radar sensing nodes, keeping mutual interference below the noise floor.
Combining spatial nulling with active baseband self-interference cancellation lets ISACFabric transmit and receive continuously on the same frequency band, doubling effective spectral efficiency versus time-division schemes.
