基于FPGA的高速自适应滤波器的实现

Implementation of high speed AF based on FPGA

在LMS算法进行变步长处理的基础上,结合驰豫超前流水线技术和时序重构技术提出了创新结构和改进算法,在FPGA的仿真综合环境中设计实现了该高速自适应滤波器,并且在AlteraDE2-70开发板上进行了板级测试。

In the foundation of varying step-size LMS algorithm ,the paper proposes new architectures and advanced algorithms combining delay leading transfer pipeline and timing refactoring ,and the simulation and synthesis of the efficient self-adaption filter realization based on FPGA is given. At last ,the system has been tested on Altera DE2-70 board.
