two systems coexist

CDMA2000 1xEV-DO is the new 3G network technology which is updated from CDMA2000 1x network. CDMA2000 1x is one of the most popular 2G mobile communication technologies. It is commonly used that the EV-DO network is either an upgrade of 1x or superposition network with 1x. EV-DO and 1x coexist thus the operators must solve the problem of online shoes store system coexistence.The paper mainly researches the interference between system CDMA2000 1x and EV-DO when the two systems coexist. Firstly, the paper introduces the research background of the hot women's dresses project, the development of mobile communication system, current research situations from both home and abroad and the source and content of this paper. Secondly, the paper introduces the characteristics and the key technologies of the CDMA system, especially the CDMA capacity planning and coverage planning technology. Then the paper analyses the classification of the wedding dresses 2nd system interference, the calculation of the interference between different cheap nike shoes systems and several types of the interference. Thirdly, the paper focuses on the research of simulation algorithm of the discount wedding prom dresses interference between different systems. Based on the theory of Monte Carlo simulation, the paper puts forward a simulation algorithm that reduces the interference among blog wedding dresses 2010 systems. By using wedding dresses 2010 software C++ Builder the paper realizes a simulation interference software platform.
