WCDMA中根升余弦滤波器的FPGA实现

Implementation of square-root raised cosine roll filter on FPGA in WCDMA

本文根据奈奎斯特(Nyquist)FIR滤波器的设计原理,设计了33阶根升余弦函数FIR滤波器,并提出了用FPGA实现其硬件电路的方案,最后用Modelsim和matlab工具进行了仿真验证。

According to the design principle of the Nyquist filter of FIR, this article design a FIR filter which uses root raised cosine function of 33 taps. We introduces optimization and implementation with FPGA and carry on verification of imitating with the Model- Sim and tool of Matlabs.
