An Interference Robust Synchronization Algorithm with Neyman-Pearson-Like Test Weighted lp-Correlation
摘要
Abstract
An interference robust synchronization algorithm with Neyman-Pearson-like test weighted lp-Correlation (lp-NPWC) for the timing synchronization of an Orthogonal Frequency Division Multiplexing (OFDM) system is presented by a Zadoff-Chu (ZC) sequence.The analytical results show that our Neyman-Pearson-like test weighted synchronization algorithm can reduce the multipath effects on the lp correlation synchronization,where p =1 or 2.Especially,when p =1,it is found that our algorithm is robust to the noise with a heavy-tailed distribution and fake peaks caused by a cyclic prefix.Both experiment and simulation results verify the effectiveness of analytical ones,while our algorithm is shown with higher synchronization accuracy than those of the known ones in literature.关键词
