摘　　要：针对扩频调制信号低功率谱密度的特点,讨论了一种基于FPGA和ADS8364的适于扩频通信系统的高速高精度数据采集方案。采用"自上而下"的设计思想和"自下而上"的实现流程,将整个系统划分为特定功能模块进行优化设计,详细介绍了各模块的设计方法和实现步骤。In view of the low power spectral density characteristic of spread spectrum signal, the implementation scheme of high-speed and high-precision data acquisition system based on FPGA and ADS8364 is discussed. It uses options of combining the ＂top-down＂ thinking and the ＂bottom-up＂ method to improve the design by dividing the system into some functional blocks.
