| 摘 要： | 本文提出一种稳定快速收敛的格型自适应ＩＩＲ滤波（ＡＩＩＲＰ）新算法。新的自适应ＩＩＲ滤波结构不同于一般的格型ＡＩＩＲＦ实现结构，它由ＡＩＩＲＦ的分子、分母多项式分别以全零点格型结构综合构成，具有结构简单、计算量少等优点。ＡＩＩＲＦ的格型结构，解决了ＡＩＩＲＦ的系统稳定性问题。新的格型算法可快速收敛于ＡＩＩＲＦ的全局无偏最优解，解决了ＰＥＡ算法的有偏及ＯＥＡ算法的局部极小点问题。计算机模拟实验结果证明了新的ＡＩＩＲＦ格型算法的有效性。

| Abstract: | A stable lattice adaptive IIR Filtering (AIIRF) is presented in this paper. The structure of the new AIIRF Lattice is different from that of conventional AIIRF lattice. It is realized using the AIIRF pole polynomial lattice and AIIRF zero polynomial lattice,thus the new lattice AIIRFhas the advantage with more simpler structure and less computation burden. Due to its lattice structure,the new AIIRF has more robust to stability.The Convergence performance of new lattice AIIRF is improved significant,it will converge to global unbiased solutin (Wiener Solution). |
