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/2017/193586

Kind Code:

A1

Abstract:

Disclosed is a signal transmission method, comprising: respectively mapping a first sequence comprising M elements and a second sequence comprising M elements to M equidistantly distributed sub-carriers, the M sub-carriers being sub-carriers on a same time domain symbol, the first sequence and the second sequence having orthogonal code division, the first sequence a0, a1, ..., aM-1 being obtained by expanding a third sequence c0, c1, ..., cK-1 having length K, the second sequence b0, b1, ..., bM-1 being obtained by expanding a fourth sequence d0, d1, ..., dK-1 having length K, M=p×K, i being a variable, the value of i being 0, 1, ..., M-1, u and v respectively being a value within 0, 1, ..., p-1, v not being equal to u; generating sending signals according to the elements on the M sub-carriers; sending the sending signals. The signal transmission method constructs two sequences having orthogonal code division via periodic repetition and phase rotation, so as to ensure that a signal transmission PAPR is relatively low when at least two signals are emitted within a time domain symbol.
