Cdma2000 1x Wireless Network Optimization

Wireless network optimization means that according certain criteria and needs, we gather parameters, analyze data and research on technologies of the network, find the reasons affecting the running qualities, adjust parameters and take some improved technologies in order to enhance the quality of the network services,make network on its best state. For CDMA mobile communication system, network optimization is very important, because the CDMA mobile communication system is interference limited communication systems, the capacity of the system is soft capacity, network optimization will not only improve the network performance and service quality, but also increase the capacity of the system. Basing on the relevant knowledge of mobile communication and network optimization, this dissertation makes a deep research on wireless network optimization of cdma2000 1x system.The main contents of this dissertation are recapitulated as follows:1. Through gathering literatures, the dissertation introduces the network performance and the key techniques of physical layer of CDMA2000 emphasized. Meanwhile, the concept classification, flow of network optimization and the network optimization of CDMA2000 1X system are also studied and generalized.2. Due to the interference of CDMA system's capacity, the multi user detection techniques can enhance the capacity of the system by eliminating multiple access interference. It also introduces the Multiple User Detection algorithm, simulation and make a conclusion.3. The preparatory work, major contents, system status diagram and practical cases of engineering optimization are introduced.4. Comparing and analysing the engineering project before and after optimization. The engineering project are summarized as well combining with the optimization.
