Design and Implementation of an IMT-2000 System based on W-CDMA

摘要

SK Telecom has made efforts to develop IMT-2000 system since 1996. As a result of an effort, the first trialsystem was implemented in 1997. In 1999, An advanced system with higher performance was developed toprovide various services and functions. This paper presents the main features and overall system architectureof the W-CDMA based IMT-2000 system developed by SK Telecom. The main purpose of this system is toverify the functions and performance of the W-CDMA based radio transmission technology. This system notonly provides internet access at 128 Kbps and real time video communication at 384 Kbps but also supportskey functions in the mobile environments including power control, handover, registration, etc.
