Mobile Communication Antenna Performance Analasis And Positoning Technology

With the rapid development of mobile communications in China for10years,the three great communications operators have already had over800billion user base,forming a very large communications market.With the increase of users of mobile communications in recent years,the number of antenna fo communications base station becomes very large.In currently used cellular mobile communications systems,antenna is the converter between the circuit signal of communications equipment and the electromagnetic waves of space radiation.The working parameters of the antenna system has an important impact for the performance of the communications network and directly affect the satisfaction of the customer experience.The traditional theory and engineering research mostly focus on the layout of the antenna system optimization problem,but pay less attention to the impact of the performance parameters of antenna itself to the communication network performance,resulting in that the problem of the performance of communication network can not be solved.In order to improve the satisfaction of customers in the communication network and the speed of solving the problems occurred in the communication network,this article researches the method to locate the problems of antenna system efficiently,with WCDMA as the background of the research.1)This article makes research of the key performance parameters of the antenna system and summeds up the list for the different communication network qualities. 2).Deduce a method of using the drive test data for regional modeling of the base station to locate the antenna problems efficiently.3).Combining the characteristics of intermodulation interference,this article makes research of using the theory of neural network to locate the problems of antenna system efficiently.Based on the implicit relationship of the network management data and antenna problems,we can make a model of neural network to achieve the goal that antenna problems can be located by the network management data.
