基于FPGA和LMS算法的系统建模

System Modeling Based on FPGA and LMS Arithmetic

自适应滤波器用于实现对未知系统的建模,用Matlab中的Simulink对LMS算法的实现方法进行仿真,在FP-GA中实现了LMS算法及其建模,并对FPGA设计的系统建模结果采用Matlab软件仿真,以增强Quartus的仿真功能,从而得到完整且直观的仿真结果。这种系统建模所采用的仿真、实现和验证方法同样适用于消除宽带信号中的窄带干扰,实现自适应谱线增强以及自适应均衡等,具有一定通用性。

The realization method of LMS arithmetic is simulated by SIMULINK in Matlab,the LMS arithmetic is realized by FPGA,and system modeling by self- adaptive filter and FPG-A, the emulational function of Quartus are enhanced by Matlab, and the result is rounded and intuitionistic. The method of emulation, realization and validation to the system modeling is the same with the elimination to narrow- hand disturb in wideband,the realization to self- adaptive equalization etc. and it has a certain universal sence.
