Abstract
A first near-field communication device is configured according to a modulation type transmitted by a second device. A decoder of the first device decodes a received signal using type-A modulation during a first time slot corresponding to the duration of a first type-A symbol. The first device determines the modulation type transmitted by the second device according to the value of the decoded symbol.
Claims23
A device, comprising:
- demodulation and decoding circuitry, which in operation, decodes received signals according to a selected modulation type of a plurality of modulation types;
- and
- modulation-type selection circuitry, coupled to the demodulation and decoding circuitry, wherein the modulation-type selection circuitry, in operation,
- controls the demodulation and decoding circuitry to decode a received signal as a type-A modulated signal for a first time slot corresponding to a duration of a type-A symbol;
- when the result of the decoding of the first time slot is 0111, selects type-A modulation as the modulation type of the received signal;
- and
- when the result of the decoding of the first time slot is 0101, selects type-C modulation at 212 kbits per second as the modulation type of the received signal.
A system, comprising:
- analog-front-end circuitry;
- and
- digital-signal-processing circuitry coupled to the analog-front-end circuitry, wherein the digital-signal-processing circuitry, in operation,
- decodes a received signal as a type-A modulated signal for a first time slot corresponding to a duration of a type-A symbol;
- when a result of the decoding of the first time slot is 0111, selects type-A modulation as the modulation type of the received signal;
- when the result of the decoding of the first time slot is 0101, selects type-C modulation at 212 kbits per second as the modulation type of the received signal;
- and
- decodes the received signal using the selected modulation type of the received signal.
A non-transitory computer-readable medium whose contents configure a near-field communication router to perform a method, the method comprising:
