Title:
CONTROL STATION, SENDING STATION, DATA TRANSMISSION SYSTEM, CONTROL CIRCUIT, STORAGE MEDIUM, AND DATA TRANSMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/210043
Kind Code:
A1
Abstract:
A data transmission system in which a sending station (300) that performs delta-sigma modulation sends data to a receiving station, wherein a control station (100) that controls the operation of the sending station (300) comprises: a frequency control unit (104) that generates channel placement information indicating the allocation of channels, which are units of frequency division, to each beam; a zero point control unit (103) that changes the zero point placement of the delta-sigma modulation and generates zero point placement information indicating the zero point placement each time a change occurs; and a computation processing unit (105) that uses the channel placement information and the zero point placement information to determine the zero point placement used by the sending station (300).
