MA网络优化中导频污染问题的研究

Network optimization of which the purpose is to improve the network communication quality is a key part of the network construction and development. Pilot pollution is one of the most important reasons that affect the service quality and capacity of network and becomes the focus problem that should be solved. The principle of the pilot pollution was analyzed, the factors which affects the formation of the pilot pollution such as terrain, environment, base station and antenna were discussed and some common solutions to the pilot pollution were summarized. Finally an actual pilot pollution case was analyzed and the corresponding solutions were proposed and tested to verify the feasibility.
