Abstract

This paper proposes a hardware platform for WCDMA baseband data transmission, which consists of USB3.0 interface, general purposes processor (GPP), and software defined radio (SDR) system. In view of the requirements of WCDMA system, the hardware platform consisting of USB3.0 controller, FPGA and DDRII was selected, which finally realized the high throughput rate and low delay transmission of baseband data of WCDMA system. The experimental results show that in this GPP software defined radio system, the interface speed of USB3.0 can reach 200MBps, and the loopback delay time of the system is about 0.7ms, which can meet the requirements of WCDMA system.
