|Title:||METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING A SIGNAL|
A signal transmitting method, comprising: a transmission device mapping a first sequence to M even number of subcarriers of 2M subcarriers, and mapping a second sequence to M odd number of said 2M subcarriers, the first sequence is one of a third sequence and a fourth sequence, the second sequence is the other one of the third sequence and the fourth sequence, the 2M subcarriers are subcarriers on the same time domain symbol, the elements of a second time domain sequence corresponding to the fourth sequence and of a first time domain sequence corresponding to the third sequence at the same time satisfy the condition that, with the exception of one complex factor, one of the first time domain sequence and second time domain sequence is an in-phase branch, and the other one is a quadrature branch; said transmission device generating a transmission signal by means of transforming the sequences mapped on the 2M subcarriers into the time domains and then transmitting the transmission signal. The described method realizes simultaneous transmission of two signals on the same time domain symbol while preserving a low peak-to-average.
