Abstract
Techniques for compressive receiving. An example RF receiver includes a plurality of digital phase shifters configured to apply a phase encoding scheme to a multi-band digital signal to produce a plurality of reference signals and a corresponding plurality of phase-encoded signals, each reference signal and each phase-encoded signal containing frequency information representing a respective sub-band of the multi-band digital signal, summers that respectively sum the plurality of reference signals and the plurality of phase-encoded signals, channelizers that divide the summed reference signal and the summed phase-encoded signal into a plurality of frequency bins, and a detector configured to detect a signal of interest and to perform delta phase measurements using the summed reference signal and the summed phase-encoded signal to estimate an original RF frequency of the detected signal of interest.
