Combinatorial mask triggering logic can make various determinations about the relationship between a digitized signal and the one or more mask triggers. The various determinations about the relationship can include considerations of both space and time. When the combinatorial trigger criteria have been satisfied, a trigger signal is generated, and the digital data associated with an incoming signal is stored to memory. The combinatorial mask triggering logic can operate on signals in the frequency domain, the time domain, or both.

  • Patent number: 9702967
    Abstract: A method for setting a detection threshold for a received signal of a frequency-modulated continuous-wave radar sensor of a motor vehicle is disclosed. In successive measuring cycles of the radar sensor in each case a radar signal is emitted into a capture zone of the radar sensor and a received signal is received, in each measuring cycle a frequency spectrum relating to the respective received signal is determined, wherein individual frequency bins of the frequency spectrum each correspond to a signal level in a range-resolution cell, and the detection threshold is set individually in each case for a subset consisting of at least one frequency bin, and in order to set the detection threshold, a noise level is determined from frequency bins of temporally preceding measuring cycles and/or from frequency bins of adjacent Doppler-resolution cells of the frequency spectrum.

  • Patent number: 9429647
    Abstract: The present disclosure discloses a system and method for. classifying Wi-Fi signals from Fourier transform samples. Generally, classifying Wi-Fi signals from Fourier transform samples includes: collecting and dividing Fourier transform samples into frequency blocks; determining the bandwidth for the Fourier transform sample; and determining whether the Fourier transform sample corresponds to a narrowband signal. Further, if a determination is made that the Fourier transform sample does not correspond to a narrowband signal, channel utilization is calculated based on a determination that the FFT sample corresponds to a Wi-Fi signal. If it is determined that the Fourier transform sample corresponds to a narrowband signal, then a determination is made that the FFT sample corresponds to a Wi-Fi signal based on certain criteria. The certain criteria may include one or more of a slope value, a number of sub-peak bins, an analysis of adjacent channels, characteristic matching, or other criteria.
