Multipath Time Delay Estimation in Multi Channel Disturbance Case
Liu Ying · Dianzi xuebao · 2001
Taking into account the multi channels disturbance and noises with the non stationary characteristic,time delay estimation based on cyclic correlation parametric approach is proposed in this paper.Multi path time delays are estimated precisely with this method,and disturbances and noises can be refrained effectively.This method has better performance than the time delay estimation based on correlative and has less calculating amount and more wide applicability than the estimation based on the higher order cumulant approach.The relevant conclusions are got and verified by the simulation experiments.
