Abstract:
A full-duplex analog relay may comprise an analog uplink relay and an analog downlink relay, and may relay signals between a transmitter and a backscatter node. The spectrum of the downlink signal transmitted by the downlink relay may be different than the spectrum of the uplink signal received by the uplink relay. Filtering may attenuate leakage from the downlink relay to the uplink relay, and vice versa. The uplink relay may create a phase offset that is opposite in sign and substantially equal in magnitude to the phase offset created by the downlink relay. The downlink and uplink relays, taken together, may created a substantially constant net phase offset. The full-duplex relay may be housed in a vehicle that moves, and may be used to determine spatial coordinates of backscatter sources that are located in the relay's environment.

Claim (Index 20):
The system of  claim 15 , wherein:\n (a) the second transceiver comprises a backscatter node; (b) the system is configured in such a way that\n (i) the downlink signals have a first spectrum when transmitted by the downlink relay, and \n (ii) the uplink signals have a second spectrum when received by the uplink relay from the second transceiver, the second spectrum being different than the first spectrum; \n (c) the downlink relay includes an analog downlink filter; (d) the uplink relay includes an analog uplink filter; and (e) the uplink and downlink filters are configured to filter the uplink and downlink signals, respectively, in such a way as to attenuate a first leakage and a second leakage, the first leakage being leakage, to the uplink relay, of downlink signals transmitted by the downlink relay, and the second leakage being leakage, to the downlink relay, of uplink signals transmitted by the uplink relay.
