Cdma2000 1x Wireless Network Optimization

Wireless network optimization is in accordance with certain criteria and needs of running networks for parameter collection, data analysis and technical research to identify the causes of the quality of network operation and parameter adjustments and some of the improved technology, the network quality of service higher, higher resource utilization, enhance network operations brand. Wireless network optimization of wireless communications engineering important part of running. For the CDMA mobile communication system, network optimization is more important, because CDMA mobile communication system is interference limited communication systems, system capacity is a soft-capacity, network optimization can not only improve the network performance and service quality, but also increase the capacity of the system. Based on the study of mobile communications and network optimization based on knowledge, combined with practical projects, cdma2000 lx system, wireless network optimization problems were studied.This paper studies are as follows:1. By collecting documents and information, focusing on the evolution of CDMA2000 standards, the key network performance and physical layer technologies, but also the concept of network optimization, classification and process of cdma2000 lx wireless network optimization has been studied and summarized.2. CDMA system capacity as the interference limited nature, the introduction of multi-user detection technology, by eliminating multiple access interference to increase the capacity of the system.3. Engineering optimization, introduced the preparations for engineering optimization, main contents and system status graph, cited the case of practical engineering optimization.4. The case of the actual project has been optimized compared before and after optimization analysis and optimization combined with practical engineering cases are summarized.
