Wireless communication device and method for spectrum sensing across multiple frequency bands

Abstract

A wireless communication device includes a MIMO antenna array with dual-polarized antennas to receive RF signals in vertical and horizontal polarizations across a plurality of frequency bands. The received RF signals are filtered to isolate signals-of-interest, down-converted and digitized to obtain digitized down-converted signals. The wireless communication device includes a processor to concurrently process the digitized down-converted signals based on configuration of multi-link operation (MLO) parameters in the wireless communication device. The processor performs cross-band correlation between the processed digitized down-converted signals of the first intermediate frequency band and second intermediate frequency band to identify related signal patterns. The processor classifies detected signals based on the cross-band correlation, null steering, and an angle-of-arrival information and controls the wireless communication device to trigger an operational response based on the classified signals and the cross-band correlation.
