Abstract
A receiver for receiving a radio frequency (RF) signal that comprises a carrier signal modulated with a baseband symbol. The receiver includes a plurality of spatially-distributed antennas to receive the RF signal; a local reference signal generator configured to generate a local reference signal; a plurality of power couplers, each power coupler having a first input connected to a respective one of the antennas to receive a respective version of the RF signal, a second input connected to the local reference signal generator to receive the local reference signal, and an output to output a corresponding coupled signal; and a differentiator circuit connected to the power coupler outputs for determining a power differential between at least one pair of the coupled signals to recover the baseband symbol from the RF signal.
