Optimum Fitting Genetic Algorithm for Multipath Mitigation in Galileo BOC (1,1) Receivers

Short delay multipath of Galileo BOC (1,1) signal can not be effectively mitigated by traditional methods.A method transforming multipath mitigation to optimum fitting is proposed.The Genetic algorthm is used in the mitigation of multipath to reduce the Galileo pseudo-range measurement error of each channel and improve positioning accuracy.The steps of the method are described,and the simulation result proves that the estimation of multipath by the method is affective.
