BACKSCATTER DEVICES AND SYSTEMS PROVIDING BACKSCATTERED SIGNALS INCLUDING OFDM PACKETS

摘要

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.
