Sony patents wireless signal method to improve time sync detection
Sony describes a method for sending wireless data that helps receiving devices lock onto the correct timing. The system combines a standard synchronization pattern with a continuous wave signal to create a frame that is easier to detect.
In the filing’s own words
The present disclosure relates to a transmission device, a transmission method, a reception device, and a reception method that make it possible to detect frame positions more favorably. A modulation signal generation section generates a complex modulation signal including a synchronization sequence; a CW signal generation section generates a complex CW signal having any frequency; a frame generation section generates a time synchronization frame for time synchronization with a reception device by superimposing the complex CW signal on the complex modulation signal; and a transmission section transmits the time synchronization frame to the reception device as a transmission signal. The technology according to the present disclosure is applicable to wireless communication systems for which the time synchronization is necessary.
What exactly they claim (claim 1)
1. A transmission device comprising: a modulation signal generation section that generates a complex modulation signal including a synchronization sequence; a CW signal generation section that generates a complex CW signal having any frequency; a frame generation section that generates a time synchronization frame for time synchronization with a reception device by superimposing the complex CW signal on the complex modulation signal; and a transmission section that transmits the time synchronization frame to the reception device as a transmission signal.
