LTE系统中DFT快速算法研究

his paper describes single-carrier frequency division multiple access (SC-FDMA) in the LTE communication system and how to implement single-carrier frequency division multiple access technology. DFT computing used in generating SC-FMDA symbols is analyzed in detail. And according to the features of DFT in LTE systems, a DFT fast algorithm based on the characteristics of DFT is used to decompose the DFT computing. This method can significantly reduce the computation of DFT in LTE system.
