Based On Multi-user Detection Technology Of Cdma Wireless Network Optimization Of Empirical Research

with China’s accession to the WTO, competition between operators, as well as the issuance of3G licenses, CDMA network of China Telecom is an integrated, expanding the user surge, network quality has become mobile operators decide the fate of the fundamental factors. Network optimization is becoming mobile operators focus of future work. Now, operators are concerned about is how the existing network infrastructure, through the optimization and improvement, thereby maximizing the potential of mining network. Network optimization objective is to improve or maintain network quality, and network quality is the result of the interaction of various factors, with the optimization of the depth and optimization technology to improve and optimize the network from the current penetration has to include market forecasting, network planning implementation of the project put into operation until every aspect of the whole cycle. For CDMA mobile communication systems, network optimization is more important, because the CDMA mobile communication system is interference limited communication systems, system capacity is soft capacity, network optimization can not only improve network performance and service quality, but also increase the capacity of the system. This paper studies the mobile communications and network optimization based on knowledge, combined with practical engineering, the system of CDMA20001x wireless network optimization problems were studied.In this paper, the wireless network optimization current development status, background, purpose and meaning were introduced, then the CDMA network and its evolution are reviewed, specifically including network theorv, technical characteristics, standards and benefits. Then describes the network optimization projects in the main content, process and specific aspects, including the setting of specific parameter’s, and details the specific focus of preparation and testing. As the capacity of CDMA system interference limited, increasing the capacity of the system to do by eliminating the multiple-access interference. in this paper the multi-user detection techniques were introduced, and algorithms and highlighted its basic concepts. Then, with the author’s own work time to the specific form of case studies, given the specific optimized test results and project examples. Finally, the sum of the full text of the specific work, and the inadequacies of the text are summarized.
