Implementation of the wideband CDMA receiver for an IMT-2000 system

This paper describes the design, implementation and testing of wideband cod e division multiple access (CDMA) base station demodulator for the internat ional mobile telecommunication-2000 (IMT-2000) system test plant based on c dma2000 radio transmission technology (RTT). The performance of the impleme nted base station demodulator is measured and compared with the theoretical performance bound. The system test plant equipped with this demodulator pr ovides 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.
