| Abstract: |
| The principle of adaptive antenna array algorithm is discussed,and then the effects of multipath interference on the performance of smart antennas is further analyzed through simulations on anti-multipath interference of smart antennas with LMS algorithm,under a multipath channel.The simulation results illustrate that the anti multipath interference performance changes with single spatial distribution and single amplitude. |
