一种基于PI技术的并行自适应滤波结构

Parallel Filtering Architecture Based on PI Technique

基于 PI技术 ,在原多项式表示的并行处理结构基础上提出了一种新的并行自适应滤波结构。新结构的复杂度远远低于基于多项式表示的并行结构 ,与普通串行的自适应 FIR滤波器相当 ,所以在保证数据通过率较高和系统功耗较低的同时 ,因为结构简单而更易于实现。 MATLAB实验仿真运行结果表明新结构算法在收敛速度上明显优于前两者 ,从而为并行自适应实时处理提供了现实的可行性。

Parallel processing is one of the main techniques in the fields of high-speed real-time signal processing. Taking the adaptive FIR filter as an example, a new parallel filtering architecture is presented by using pipelining/interleaving(PI) technique. Compared with the original architecture, it is very simple and suitable for the real time applications. Computational simulations in MATLAB show that the new algorithm is better than the original ones in performance.
