The Optimization Of The Mobile Base Antenna

The mobile communication development today is developing rapidly, and unpredictablely. The demand of wireless grows day by day, and the importance of wireless network optimization is self-evident. As the communication technology improving and the society advancing, the requirements of the quality of the network of users are more and more high, mobile operators also begin to pay more and more attention to the quality of the mobile network, the network optimization is covered in conditions such as improving mobile network quality in the most direct and the most effective way. Network optimization of mobile communication network is the important key technology, base station antennas optimization is the main method of network optimization.In this thesis mobile base antenna optimization is discussed. the first, through the analysis of the GSM network optimization problems, especially the antenna problem analysis, we did a lot of research aimed at cellular mobile communication network planning and optimization under the antenna obliquity, azimuth automatically adjust the problem. By constructing a antenna automatic adjustment system to optimize the view of the antenna configuration in base of the mobile network, compared with the traditional manual adjustment of the way the antenna point,it can not just reduce maintenance and operation cost, but improve the internet service quality. Second, It is to establish model, design and research three kinds of heuristic algorithm optimizing the antenna (ant colony optimization algorithm, simulated annealing algorithm, a search algorithm), and the improvement of the optimization model and the application of heuristic algorithm. Finally,presents a series of simulation results and analysis.Antenna optimization in mobile communication network is important. The adjustment of the parameters of the antenna elevation Angle and azimuth can lead direct impact on the communication network covering quality and system capacity. Antenna optimization is a complex high dimensional optimization problem, such problem can only be solved by heuristic optimization algorithm. Heuristic optimization algorithm and Confinement search algorithm are more effective in the optimization of antenna mobile base in the three kind of heuristic algorithm, I think the simulated annealing algorithm and confinement search algorithm in optimization is the most obvious effect.
