| Abstract: | Intelligent antenna can reduce the impact caused by the multipath effectively,it also can eliminate and restrict the interference,and ultimately to reduce the bit error rate at the receiver.To achieve this purpose and improve the system performance,this paper proposes an adaptive intelligent antenna based on the least mean square,and firstly,introduces the basic principles of adaptive intelligent antenna;Secondly,analyses the least mean square algorithm and the adaptive filter ;Finally,the proposed adaptive algorithm in this paper is simulated.The simulation results illustrate that：the using of adaptive intelligent antenna has a lower bit error rate than that is not used at the receiver,so we make a conclusion that the adaptive alogrithm applied in the intelligent antenna system is effective and practical. |
