Wireless communication device and method for adaptive RF spectrum analysis

A method for adaptive RF spectrum analysis, the method comprising:

• in a wireless communication device:
• receiving radio frequency (RF) signals in vertical and horizontal polarizations across a plurality of frequency bands;
• applying band-specific filtering to the received RF signals to isolate signals-of-interest;
• down-converting and digitizing the signals-of-interest to predefined intermediate frequencies to obtain digitized down-converted signals, wherein the RF front-end comprises a WLAN radio including distinct RF chains for concurrent operations across different frequency bands;
• setting a plurality of operational parameters to process digitized down-converted signals, wherein the digitized down-converted signals are input signals in a plurality of different intermediate frequency bands;
• processing the digitized down-converted signals across a plurality of distinct signal domains;
• determining one or more signal patterns based on a generated fused feature vector for each intermediate frequency band of the plurality of different intermediate frequency bands;
• generating feedback data based on the determined one or more signal patterns and processing performance metrics of the wireless communication device;
• and
• detecting a jamming signal and perform a jamming suppression of the detected jamming signal based on the determined one or more signal patterns, the generated feedback data, and a periodic adjustment of the plurality of operational parameters.
