Abstract

The present invention discloses a method for processing signals to be transmitted, suitable for application scenes that the signal to be transmitted is a ZC sequence and the ZC sequence needs to be transformed into a corresponding DFT sequence. The method determines a multiplication inverse element u<-1> of the ZC sequence and a for making an equality of u*u<-1> = a*Nzc + 1 to be tenable according to a physical root sequence number u of the ZC sequence to be transmitted, and calculates a sequence sum of the ZC sequency: Xn(0) and generates a conjugation sequence x<*>u<-1>(k) of xu<-1>(k), then judges according to the odevity of u<-1> and a, when a is odd and u<-1> is even, a formula (I) is used as the DFT sequence of the ZC sequency, otherwise a formula (II) is used as the DFT sequence ofthe ZC sequence; wherein Cv is a cyclic shift value of the ZC sequence. By means of the invention, it is capable of reducing operation complex degrees and operation quantities of a signal transmission terminal, and improving efficiency of signal transmission of the signal transmission terminal.

Description

technical field The present invention relates to LTE technology, in particular to a method for processing signals to be sent. Background technique Most of the current fourth-generation mobile communication standards are based on Orthogonal Frequency Division Multiple Access (OFDMA) technology. Since OFDMA is sensitive to synchronization, a specific synchronization signal needs to be transmitted on OFDM subcarriers. Considering the power and computation-constrained characteristics of a mobile station (UE), it is necessary to provide an efficient synchronization signal generation method at the transmitting end (ie: UE end) of the uplink of the communication system. The Zadoff-Chu (ZC) sequence has good characteristics of ideal autocorrelation (ACF) and constant modulus cross correlation (CCF). Among them, the constant modulus cross correlation characteristic can reduce the interference between access users, and the ideal autocorrelation characteristic is easy for the receiver...
