Ofdm system is capable of providing bigger coverage area, better transmission quality, higher data rate and frequency spectrum effect Rate.However, since OFDM symbol is to be formed by stacking by multiple independences through the sub-carrier signal of ovennodulation, when each subcarrier phase When position is same or similar, superposed signal is subject to the modulation of identical initial phase signal, to generate biggish instantaneous function Thus rate peak value further brings higher papr (PAPR, Peak to Average Power Ratio). Since the dynamic range of general power amplifier is all limited, so PAPR bigger ofdm signal easily ingoing power Amplifier nonlinearity region causes signal to generate non-linear distortion, causes apparent spread spectrum interference and inband signaling Distortion, leads to whole system performance degradation.The major technique that high PAPR has become OFDM hinders.

I.e. in the embodiment of the present invention, the selected phaseFromMiddle selection, N are the tune The number for all predetermined phases that symbol sebolic addressing processed can rotate, N are the positive integer more than or equal to 1, and m is the modulation symbol Sequence rotates in the transmission symbol constituted after the predetermined phase corresponding to the smallest transmission symbol of power amplifier characterizing metric parameter The serial number of rotatable phase, the value range of m are as follows: 0~N-1, i.e. M can be from 0,1,2 ... chooses in N-1.

Wherein, N can be configured by network side equipment, or by providing in agreement, alternatively, being assisted by network side equipment and terminal Quotient etc..

Above-mentioned selected phaseIt can be determined by following manner:

Successively fromOne phase of middle selection (certainly, in some other embodiment of the invention, The sequence for choosing phase can not also be limited)；

The modulation symbol sequence is rotated to the phase of the selection, the symbol sebolic addressing after generating phase rotation；
