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 6):
A system comprising two or more full-duplex analog relays, wherein:\n (a) each full-duplex analog relay, respectively, in the system comprises\n (i) an analog downlink relay that is configured to receive and retransmit wireless downlink signals, and \n (ii) an analog uplink relay that is configured to receive and retransmit wireless uplink signals; and \n (b) the system is configured to relay the downlink signals and the uplink signals in such a way that\n (i) a first full-duplex analog relay in the system receives the downlink signals from a first transmitter, \n (ii) a second full-duplex analog relay in the system transmits the downlink signals to a backscatter node, \n (iii) the second full-duplex analog relay receives the uplink signals from the backscatter node, \n (iv) the first full-duplex analog relay transmits the uplink signals to the first transmitter, and \n (v) for each respective full-duplex analog relay in the system\n (A) the downlink relay of the respective full-duplex relay transmits at a center frequency that is different than at which all other downlink relays in the system transmit, \n (B) the uplink relay of the respective full-duplex relay transmits at a center frequency that is different than at which all other uplink relays in the system transmit, \n (C) the downlink signals transmitted by the downlink relay of the respective full-duplex relay have a first spectrum, \n (D) the uplink signals received by the uplink relay of the respective full-duplex relay have a second spectrum that is different than the first spectrum, \n (E) the downlink relay of the respective full-duplex relay includes an analog downlink filter, \n (F) the uplink relay of the respective full-duplex relay includes an analog uplink filter, and \n (G) 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 the respective full-duplex relay, of downlink signals transmitted by the downlink relay of the respective full-duplex relay, and the second leakage being leakage, to the downlink relay of the respective full-duplex relay, of uplink signals transmitted by the uplink relay of the respective full-duplex relay.
