一种新的DFT频偏估计算法
A NEW DFT FREQUENCY OFFSET ESTIMATION ALGORITHM
摘要
Abstract
In this paper we propose a new carrier frequency offset estimation algorithm in light of the carrier frequency synchronisation in wireless digital communications.The new algorithm can work out the carrier frequency offset in a wider frequency offset range by using discrete Fourier transform (DFT) algorithm and through iterative algorithm.Moreover,its estimation accuracy improves a lot than the DFT algorithm.This algorithm does not need to increase the data length of DFT,and is suitable for burst working mode.Finally,a Monte Carlo simulation experiment has been done,the simulation results show that the new algorithm not only has a wide estimation range,its estimation accuracy is also high as well.关键词
