The Cdma The Gota Wireless Network Simulation System Algorithm

With the coming 3G wave, domestic and overseas operators begin to construct their 3G wireless networks. During this period, network planning is a very important work not just before sell but also after sell. However, the traditional planning methods such as perambulation, link calculation can't ensure the reliability and quality of a planning scheme. Under this background, many overseas software corporations have invented wireless network simulation software to shorten the planning hours keep the rationality of a planning scheme, and most important of all, show the intuitionistic forecasts to operators. No domestic corporation has set foot in it until now. However, existing overseas simulation softwares have some problems. For example, they are all very expensive and usually have big error in data simulation. At the same time, no software can make wireless simulation for GoTa system from ZTE. Under this background, we have to design new simulation software for CDMA data service and GoTa system.The dissertation starts with the research of random factors in wireless network, electromagnetic wave spread, traffic mode and Monte Carl method, and then designs an integrated CDMA simulation arithmetic, later tests it at Matlab, balances it with existing software and practice data, finally investigates the theory and traffic mode of GoTa, designs GoTa simulation arithmetic.The main results are as follows:Random factors in wireless network are evaluated; the most important factors are selected, and simulated with appropriate mathematics model.CDMA simulation arithmetic is designed.CDMA data rate indication arithmetic is designed.GoTa simulation arithmetic is designed.
