Abstract
An electronic device receives wireless signals encoded with data in an amplitude-shift keying format. The electronic device passes the wireless signals through a low-pass filter. The low-pass filter has a cutoff frequency between a first frequency associated with data values of a first type and a second frequency associated with data values of a second type. The low-pass filter has the effect of changing the wireless signal from the amplitude-shift keying format to an on-off keying format without losing the data. The electronic device decodes the data from the wireless signal in the on-off keying format.
Claims20
A method, comprising:
- receiving, with a first electronic device, a carrier signal transmitted from a second electronic device and including data encoded with an amplitude-shift keying scheme;
- generating, from the carrier signal with the first electronic device, an on-off keying signal by passing the carrier signal through a low-pass filter;
- and
- decoding, with the first electronic device, the data from the on-off keying signal.
An electronic device, comprising:
- an antenna configured to receive, from a transmitting electronic device, a carrier signal including data encoded with an amplitude-shift keying scheme;
- a low-pass filter configured to receive the carrier signal and to generate an on-off keying signal from the carrier signal;
- and
- a controller configured to decode the data from the on-off keying signal.
A method, comprising:
- receiving, with an electronic device, a carrier signal encoded with data;
- harvesting energy from the carrier signal with the electronic device;
- passing the carrier signal through a low-pass filter having a cutoff frequency between a first frequency associated with data values of a first type and a second frequency associated with data values of a second type;
- and
- decoding the data from the carrier signal after passing the carrier signal through the low-pass filter.
