Title:
WIRELESS TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/245718
Kind Code:
A1
Abstract:
This wireless transmission method includes: a modulation signal creation step for creating a modulation signal from transmission data and a symbol clock; a narrow band synchronization signal creation step for creating, from the symbol clock, a narrow band synchronization signal that is continuously present and spans the entire period of a frame when viewed from the time axis; a transmission signal creation step for creating a transmission signal in which a carrier signal is superposed on the modulation signal and the narrow band synchronization signal; and a transmission step for transmitting the transmission signal. According to this invention, it is possible to provide a wireless transmission method which can achieve synchronization with a simple reception device configuration and which is unlikely to be affected by interference or the like.
