Research Of Base Stations And Netwrok Optimization For CDMA System

Into the twenty-first century wireless mobile communication technology, rapid development, the development of 3G technology is more attracted our attention. China Mobile Communications industry's Big Three companies were using different CDMA Technology:China Mobile Communications Corporation based on technical standard TD-SCDMA, China Telecom Group technical standard based on CDMA2000, China Unicom Group, the adoption of WCDMA technology standard. At the same time as a new round of construction of large-scale commercial 3G base stations and network optimization are also about to start.This paper from the CDMA base station system structure and proceed to the CDMA network optimization are introduced. Base station system which focuses on the structureand construction method, and network parameters were optimized on the base of knowledge.Finally, discuss the end of the CDMA wireless network construction and optimization of siting and development of an overview of trends. I CDMA1x with China Unicom to provide the network engineering practice, some areas of Guangdong Province, the network testing and related data collection, and so the network quality and performance analysis of the adjustment program to develop and optimize the proposed measures.
