Abstract:
Apparatuses, systems, ambient RF backscatter transceivers, and methods for communicating using MIMO and spread spectrum coding of backscattered ambient RF signals are described. An example system may include an ambient RF backscatter transceiver that include an antenna configured to receive a backscattered ambient radio frequency (RF) signal, and a receiver coupled to the antenna. The receiver may be configured to demodulate the backscattered ambient RF signal using one of multiple input, multiple output multiplexing demodulation or spread spectrum code demodulation to retrieve the first data. The backscattered ambient RF signal may be generated by backscattering an ambient RF signal at a first frequency. The ambient RF signal may be configured to provide other data at a second frequency.

Claim (Index 16):
The ambient RF backscatter transceiver of  claim 12 , wherein the spread spectrum code demodulation circuit further comprises a summation circuit configured to add a magnitude of an in-phase component and a magnitude of a quadrature-phase component to produce a sum signal, wherein the summation circuit comprises:\n an amplifier configured to provide the sum signal at an output based on the magnitude of the in-phase component and the magnitude of the quadrature-phase component received at a first input, wherein a second input of the amplifier is coupled to a reference node; a first resistor configured to provide the magnitude of the in-phase signal to the first input of the amplifier; and a second resistor configured to provide the magnitude of the quadrature-phase signal to the first input of the amplifier.
