1. A receiver for wireless power and broadband data, comprising:
an energy harvester to harvest the wireless power;
one or more radio-frequency frontends (one or more RF frontends) configured to down-convert a frequency band received from a transmitter to a receiver intermediate frequency (a receiver IF) that is frequency and phase aligned with a transmitter IF, wherein the frequency band includes the broadband data and the wireless power modulated on multiple subcarriers, the multiple subcarriers being orthogonal to each other;
one or more second-level demodulator(s), coupled with the one or more RF frontends, wherein a second-level demodulator is configured to demodulate a stream of complex values from the down-converted frequency band, the complex values including real values and imaginary values;
a subcarriers demodulator coupled with the one or more second-level demodulator(s) and configured to convert the complex values from a time domain to a frequency domain and to output a series of subcarrier specifications; and
a first-level demodulator to convert the series of subcarrier specifications to data bits that include the broadband data.
