Abstract:
A receiver includes a bandpass filter module, a sample and hold module, a discrete time bandpass filter module, a discrete time notch filter module, a combining module, and a conversion module. The bandpass filter module filters an inbound wireless that includes a desired signal component and an undesired signal component. The sample and hold module is operable to sample and hold the filtered inbound wireless signal to produce a frequency domain sample pulse train. The discrete time bandpass filter module bandpass filters the frequency domain sample pulse train to produce a bandpass filtered sample pulse. The discrete time notch filter module notch filters the frequency domain sample pulse train to produce a notched filtered sample pulse. The combining module combines the bandpass filtered sample pulse and the notched filtered sample pulse to produce a filtered inbound signal. The conversion module converts the filtered inbound signal into an inbound baseband signal.
