Pla Information · Application of Electronic Technique · 2011
A multipath time-delay model of wireless channel was proposed,by which the time-delay estimation was converted into spectrum estimation.Then,MUSIC and root MUSIC algorithm with super-resolution ability were applied to the problem above.The feasibility of estimating multipath time-delays based on single measurement data was discussed.Meanwhile,the simulation performance of applying MUSIC and root MUSIC algorithm to the model proposed in the paper was presented.The simulation results showed that the proposed method owned super-resolution ability and robust in estimation of multipath time-delay.
