Patent ID: 8121172

Claim:
A surface acoustic wave (SAW) correlator-based receiver comprising: a splitter coupled to an antenna and to a first chirp correlator and a second chirp correlator, the splitter configured to split a signal received by the antenna into a first signal and a second signal; the first chirp correlator coupled to the splitter and configured to compress the first signal and the second chirp correlator coupled to the splitter and configured to compress the second signal, wherein the first and second chirp correlators are configured to be paired with a first and second chirp expander of a SAW expander-based transmitter, respectively; a plurality of adaptive starting gate blocks coupled to the first and second chirp correlators and configured to mitigate interference in the first and second signals; and a plurality of demodulation circuits coupled to the plurality of adaptive starting gate blocks and configured to demodulate the first and second signals to produce a detected output.
