Title: METHOD, DEVICE AND SYSTEM FOR SENDING AND DEMODULATING DATA
Abstract:
Disclosed are a method, device and system for sending and demodulating data. The method comprises: a sending device acquiring determination information about a cyclic prefix (CP) length, wherein the determination information about the CP length comprises at least one item of quantity information about data streams of data sent by the sending device, type information about the data, information about a distance between the sending device and a receiving device, width information about a wave beam transmitted by the sending device, type information about the wave beam and power information about the wave beam; the sending device determining a first length of a CP according to the determination information about the CP length; and the sending device sending the data to the receiving device, wherein the CP with the first length is added to the data. By adopting the present invention, the CP length can be dynamically determined according to determination information about the CP length.
