Design and Implement of Programmable FIR Filter with High Performance Based on Stratix II

详细介绍了一种基于Stratix II的高性能、系数可编程FIR滤波器的设计及实现方法,滤波器具有与微处理器兼容的编程接口,可以对滤波器系数实现动态编程。Quartus II的仿真结果表明了该方法的可行性,性能完全满足设计要求。该设计在传统的自适应滤波以及崭新的认知无线电(CR)[1]领域都具有重要的应用价值。

A method of the design and implement of programmable FIR filter with high performance,and with the coefficients programmable is introduced in detail. The filter has the interface compatible with universal microcontrollers, by which the coefficients of the filter can be programmed dynamically. The simulated result of Quartus Ⅱ shows the feasibility of this method and that the performance reaches the demand completely. The design plays an important role in the practical fields of traditional adaptive filter and new Cognitive Radio （CR）.
