Title:
DATA MODULATION METHOD, DATA PROCESSING METHOD, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/237518
Kind Code:
A1
Abstract:
The embodiments of the present application are applicable to the technical field of communications, and provide a data modulation method, a data processing method, a device, and a storage medium. The data modulation method is applied to a first electronic device, and the first electronic device performs Bluetooth communication with a second electronic device. The data modulation method comprises: determining a bit stream corresponding to the value of an RI field in a Bluetooth data packet to be sent, the Bluetooth data packet also comprising a frame body, and the value of the RI field being used to indicate the modulation means and encoding rate of the frame body; and modulating the bit stream to generate a modulation symbol sequence, a first bit length corresponding to the modulation symbol sequence being greater than a second bit length of the RI field. A modulation symbol sequence obtained by modulating an RI field has a spread spectrum compared to the RI field, which improves the demodulation performance after the RI field has undergone spectrum spreading and improves the transmission success rate of a Bluetooth data packet.
