摘要
本文以宽带接收高速数字处理技术为基础，深入研究了接收机系统的原理和组成，对高速率下变频滤波技术做了研究和设计。针对下变频技术提出了一种可在FPGA等数字器件上运行的多相变频+多相滤波结构，实现射频信号直接采样处理，并通过MATLAB仿真验证可行性。
The paper in-deep studied the principles and composition of the receiver system based on broadband receiver and high-speed digital processing technology.Then,the paper researches and designs the down-conversion filtering technology in high-speed.Simulation and testing a run in the FPGA digital devices multiphase conversion+multiphase filter structure to implement RF sampling directly at the back-end of antenna in MATLAB.
