| Abstract: | The multipath signal DOA(Direction of Arrival) estimations in mobile communication are discussed in this paper.Some typical algorithms are reviewed in brief first,and the model of multipath signals received by array antennas is described.The algorithm on multipath signal DOA estimation based on time averaging is introduced;also,a problem existing in this method is pointed out;an effective method for solving this problem is raised as well.Finally,the simulation results verifying the theoretical analysis are presented. |
