| 摘 要： | 为了产生调制信号的码元速率能在大范围内实时可变,采用插值滤波技术——多级积分梳状滤波器。在分析多级CIC滤波器的结构和特性的基础上,阐述了一种利用Hogenauer＂剪除＂理论实现多级CIC滤波器的高效FPGA实现方法,并通过XILINX的时序仿真分析验证了该方法的正确性和可行性,实际中可以推广应用。

| Abstract: | This paper proposes a interpolation filter technology with that the chip-rate of modulated signal can be adjusted in large scale.On the base of the analysis of structure and characteristic,it is introduced that a high efficiency FPGA implementation of multilevel CIC filter using Hogenauer theory.The method has been verified with XILINX timing simulation. It can be popularize and applied in practice. |
