Abstract: Examples of digital architectures for OFDM backscatter communication are described herein that use RF switches and discrete loads to implement digitally controlled single-sideband OFDM backscatter devices. One or more transforms may be implemented, including one or more IFFTs, LUTs, and/or numerically-controlled oscillators using one or more sine LUTs.
