摘　　要：数据采集与处理系统的设计是现代信号处理系统的基础,被广泛应用于雷达、通信、图像处理、遥感遥测等领域。在对WCDMA数字基带接收机的设计中,提出了一种基于FPGA和DSP的高速数据采集方案。该方案将A/D采样的数据送往FPGA,经过FPGA预处理后送到DSP,最终通过CPCI接口送到主控台。详细介绍了设计思想、具体的硬件连接以及FPGA设计的仿真结果。Data acqusition and processing system is basical in modern signal processing system,it is widely applied in fields of radar, communication,image processing and remote tolemetry. In the design of WCDMA digital baseband receiver, a precept of high speed data acquisition system based on FPGA and DSP is proposed. The data acquired by ADC is transferred to FPGA, }hen transferred to DSP after pri - processed by FPGA and finally to console via the interface of CPCI. In the paper, the design idea, the connection between hardware and the simulation results are introduced in detail.
