基于TK能量算子的OFDM时延估计算法
OFDM time of arrival estimation based on TK energy operator
摘要
Abstract
In order to improve anti-noise performance of OFDM signal TOA estimation,this paper proposed TK-ESPRIT algorithm by introducing TK energy operator based on ESPRIT.TK operator could track the instantaneous change of the signal.With this character,TK-ESPRIT algorithm processed the signal correlation function initially and made the correlation function peak more obvious,then built an eigenvalue matrix,and used the ESPRIT algorithm to perform TOA estimation.The simulation results show that TK-ESPRIT algorithm can effectively improve estimation precision compared to currently algorithm.关键词
