基带信号数字滤波器的FPGA实现

FPGA Realization of Digital Filter for I/Q Baseband Generator

主要介绍了用于通信 I/ Q基带信号发生器中预调制数字滤波器的特点 ,以及利用统一硬件平台——一片现场可编程器件 FPGA实现“高斯 (Gaussian)”、“奈奎斯特 (Nyquist)”、“平方根奈奎斯特 (Root Nyquist)”、“矩形 (Rectangular)”等四种滤波器的原理和电路。

It describes the characters of four types of pre-modulation filters for baseband generator, such as Gaussian, Nyquist, Root-Nyquist and rectangular. Filters' parameters can be changed by software, and four types of user-defined filters are realized using FPGA.
