Abstract:
1. A radio transceiver, comprising: radio from end circuitry operable to produce an ingoing communication signal having in-phase and quadrature-phase components on one or more receive signal paths; analog-to-digital converter (ADC) operatively coupled to receive the ingoing communication signal, the ADC producing an ingoing digital signal having digital in-phase and quadrature-phase signal components; one or more processors for processing the ingoing digital signal, wherein the one or more processors inhibit transmission of outgoing digital signals over frequency bands overlapping with radar frequency bands in response to detection of a traditional radar signal or in response to detection of a non-traditional radar signal; a radar detection block operably disposed within each of the one or more receive signal paths to receive the ingoing digital signal and operable to detect presence of the traditional radar signal and the non-traditional radar signal in the ingoing digital signal, wherein the radar detection block: detects presence of the traditional radar signal in the ingoing digital signal by detecting pulses having a period that corresponds to traditional radar signals; and detects presence of the non-traditional radar signal in the ingoing digital signal by detecting pulses having a period that is substantially greater than pulses for traditional radar signals and by determining that the detected pulses having a period that is substantially greater than pulses for traditional radar signals are frequency modulation (FM) modulated.
