SIGNAL TRANSMISSION METHOD, SENDING END AND RECEIVING END

Title:

SIGNAL TRANSMISSION METHOD, SENDING END AND RECEIVING END

Document Type and Number:

WIPO Patent Application WO/2017/193867

Kind Code:

A1

Abstract:

Disclosed is a signal transmission method, comprising: mapping a first sequence to a first sub-carrier set, and mapping a second sequence to a second sub-carrier set, the first sub-carrier set and the second sub-carrier set not including the same sub-carriers, the included sub-carriers being sub-carriers on a same time domain symbol, the sub-carriers of the first sub-carrier set and the sub-carriers of the second sub-carrier set respectively being equidistantly distributed sub-carriers, the first sequence being a Fourier transform sequence of a third sequence, the second sequence being a Fourier transform sequence of a fourth sequence, elements of the third sequence and the fourth sequence at a same position being non-simultaneous non-zero elements, the third sequence and the fourth sequence being sequences having at least one element which is a non-zero element; transforming the elements on the sub-carriers to the time domain, and generating sending signals; sending the sending signals. The method ensures that when at least two signals are emitted within a symbol, a PAPR is relatively low and mutual interference is low after the signals have passed through a channel.
