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):
A method comprising:\n receiving a backscattered radio frequency (RF) signal encoded with first data at a first frequency, the RF signal modulated to provide second data at a second frequency, and wherein the backscattered RF signal was modulated at a chip rate and a chip duration; computing, over the chip duration, an average, of I and Q values of an envelope signal, the envelope signal based on the backscattered RF signal; demodulating the backscattered ambient RF signal based partly on the average of the I and Q values of the envelope signal; and retrieving the first data based on a demodulated backscattered ambient RF signal.
