Wireless communication device and method for wideband spectrum monitoring

Abstract

A wireless communication device includes RF input to receive RF signals in a range of DC to 300 GHz. The wireless communication device includes RF front-end that includes plurality of band filters to apply band-specific filtering operation to the received RF signals to obtain filtered RF signals. A local oscillator generates tunable local oscillator frequencies above a threshold frequency. The wireless communication device includes circuitry to execute a frequency shifting operation in one or more frequency conversion stages in which one or more tuned local oscillator frequencies above the threshold frequency are injected at the circuitry to push image frequencies above the threshold frequency and shift the filtered RF signals to predefined intermediate frequencies. The filtered RF signals are digitized and a processor concurrently processes the digitized down-converted signals across predefined intermediate frequencies, and identify coordinated transmission patterns based on energy correlations from real-time spectrum energy detection.
