Abstract

We have proposed the programmable test beds that present the system-level environment to verify and analyze the performance of baseband MODEM schemes and RF/IF hardware for Wideband CDMA (W-CDMA), PCS, CDMA2000, and IMT2000 systems. These test beds have been implemented with 10 FPGAs for channel CODEC and commercial components for RF/IF transceiver. The DSP boards for real-time H.263 encoding/decoding and hardware channel-emulator have been also used. Therefore, our test beds allow the rapid development of each block and enable to reduce Turn-Around-Time (TAT) by easily analyzing the multimedia data communication systems up to 1 Mbps/20 Mcps. The measurement results show that the performance of our test beds is identical to that of commercial CDMA systems in restrict experimental environments
