Abstract

See full text

A receiver, including: a local oscillator (LO) configured to generate a signal with a frequency; a mixer coupled to the LO, the mixer configured to change a first frequency of an input signal to a second frequency based on the generated signal; a baseband filter coupled to the mixer and having a bandwidth; and a controller coupled to the local oscillator, the controller configured to adjust the frequency of the signal to shift the second frequency of the input signal to a third frequency in response to a presence of one or more intra-band jammers that fall within the bandwidth of the baseband filter so that a respective image of the one or more intra-band jammers avoids failing into a respective one of a plurality wanted signals in the input signal.
