摘要
FIR滤波器能够实现线性相位特性,可以做到无相位失真,而广泛应用于现代信号处理领域。运用FPGA可编程的特点,采用分布式算法,实现高速有限脉冲响应(FIR)滤波器,仿真结果和板级测试表明这种方法快速,消耗硬件资源少。
Realization of digital Finite-impulse-Response（FIR） filter are so important issue for digital communications and signal processing application. As its good line phase character, FIR filter can avoid phase distortion. The filter structure is based on Distributed Arithmetic（DA） ,which is able to calculate the inner product by shifting and accumulating of partial products and storing in look-up table. In this paper an FPGA-base system is presented.. The simulation and experimental results verify that this strategy possess good time closure and less resource usage.
