Wireless Network Communication Technology Research And Application

Modern mobile communication technology started in 1920's. During these 80 years, mobile communication technology have changed from analog to digital. Personal communication and integrated service are the main ideal of people about mobile communication. It becomes a key technic to realize personal communication.The primary ITU objectives for the 3rd Generation mobile communication system are flexible and seamless global service provision and improved operational efficiencies, particularly for data and multimedia services. On the background of 3rd Generation mobile communication system, the work of this thesis is below:1) Generally introduce the background of wireless communication and the main characteristics & development targets. Does some research on the basic principle of CDMA, the system architecture of CDMA, and the call processing of CDMA.2) Primarily analyze and discuss the CDMA network protocol of the 3rd Generation mobile communication system, the core network layout of the 3rd Generation mobile communication system. Analyze the system protocol of CDMA and its applications and complete the call processing of forward traffic channel.3) Explain and analyze CDMA operating system-REX system. Design and complete the tasks processing of REX system. Finally, some expectation for CDMA2000 and 3G system was given.
