Design and implementation of a wideband CDMA demodulator for an IMT-2000 system

This paper describes the design, implementation and testing of wideband code division multiple access (CDMA) base station demodulator for the International Mobile Telecommunication-2000 (IMT-2000) system test plant based on cdma2000 radio transmission technology (RTT). The performance of the implemented base station demodulator is measured and compared with the theoretical performance bound. The system test plant equipped with this demodulator provides wireless services, such as high quality speech (9.6 kbps), real-time video (384 kbps) and Internet protocol (IP) based data services (144 kbps) in a mobile radio environment.
