  • Circuits for identifying interferers using compressed-sampling
    Patent number: 11374599
    Abstract: Circuits for identifying interferers using compressed-sampling, comprising: a low noise amplifier (LNA); a passive mixer having a first input coupled to an output of the LNA; a local oscillator (LO) source having an output coupled to a second input of the passive mixer; a low pass filter having an input coupled to an output of the passive mixer; an analog-to-digital converter (ADC) having an input coupled to the output of the low pass filter; a digital baseband (DBB) circuit having an input coupled to an output of the ADC; and a compression-sampling digital-signal-processor (DSP) having an input coupled to the output of the DBB circuit, wherein the compression-sampling DSP is configured to output identifiers of frequency locations of interferers, wherein, in a first mode, the LO source outputs a modulated LO signal that is formed by modulating an LO signal with a pseudo-random sequence.
