Abstract:
Examples described herein include backscatter devices which may transmit orthogonal frequency division multiplexing (OFDM) signals. Techniques for complex analog backscatter are described. Examples of impedance circuitry are described which may be used to provide real and imaginary components of impedance in accordance with inphase and quadrature bits.

Claim (Index 10):
A system comprising:\n a helper device configured to transmit a carrier signal; and a backscatter device comprising:\n an antenna positioned such that the carrier signal is incident on the antenna; \n baseband circuitry configured to provide inphase bits and quadrature bits based on data for transmission; and \n impedance circuitry configured to provide a real component of antenna impedance corresponding to the inphase bits and a complex component of the antenna impedance corresponding to the quadrature bits, such that the backscatter device is configured to backscatter the carrier signal to form a backscatter signal including orthogonal frequency division multiplexing (OFDM) packets.
