Research On WCDMA Network Pilot Frequency Pollution Problems And Solutions

In a period of rapid development of China Mobile communication, the communication network is facing severe challenges. Due to the popularity of the network, the problem of3G mobile communication base station construction of large area, more and more diversified and complicated. Network optimization plays an important role in the operation of the whole network, the traditional approach has been unable to reach the optimization to improve the network quality requirements, develop the optimization and innovation of more perfect in the optimization of the actual work of seeking more simple, economical and practical optimization method has becomes the network optimization staff need to find the direction.4G era has become the development trend of mobile communication network, and WCDMA network as the main carrier of the present stage still service of mobile network. The construction and maintenance of good WCDMA network is still the main work of operators, in network optimization, solve the pilot frequency pollution problem is to improve the network quality, one of the important work to improve the network environment.WCDMA system is one of the most mature of the global mobile communication system, it improves the traditional communication mode of communication network of previous generations, providing greater system capacity, more business and more rapid rate. In the current network operation and maintenance of research on WCDMA network better is the primary responsibility of operatorsand technical personnel, in the network optimization ideas and better way to improve and perfect the communication network in the process of look forward to,hope that through continuous efforts to create a perfect WCDMA network, gives the user the most satisfying experience.WCDMA; is a self-interference system, interference of the network will bring many negative effects to performance and network capacity. The interference of pilot pollution is the most significant problem in WCDMA system. To solute the pilot pollution problem is one of the most important works in network optimization. The purpose of this investigation is trying to find the ways and solve the pilot pollution problem of wireless network in use of technological means and improve the quality of the network and user satisfaction.The research is study on the reasons and solving measures of pilot pollution in WCDMA system. This thesis discribed the solutions to the pilot pollution base on the optimizationof the network parameters,optimization of network sources and antenna system adjustment etc.At last we used the best combined solution to the ShenYang WCDMA network and proved the combined solution is effective.
