Abstract
A communication method and apparatus are provided, to improve frequency shift keying (FSK) demodulation performance of a low-power device. After determining at least two orthogonal frequency division multiplexing (OFDM) subcarriers, a first device sends an FSK signal to a second device on the at least two OFDM subcarriers, and the second device demodulates the FSK signal. In this way, FSK transmission of a low-power receiver can be compatible with OFDM, so that the FSK demodulation performance can be improved.
Claims20
A communication method, comprising:
- determining at least two orthogonal frequency division multiplexing (OFDM) subcarriers;
- and
- sending a frequency shift keying (FSK) signal to a second device on the at least two OFDM subcarriers.
A communication method, comprising:
- receiving, on at least two orthogonal frequency division multiplexing (OFDM) subcarriers, a frequency shift keying (FSK) signal sent by a first device;
- and
- demodulating the FSK signal.
An apparatus, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and having program instructions stored thereon which, when executed by the at least one processor, cause the apparatus to:
- receive, on at least two orthogonal frequency division multiplexing (OFDM) subcarriers, a frequency shift keying (FSK) signal sent by a first device;
- and
- demodulate the FSK signal.
