Adaptive IIR filters can be useful in many signal processing and communication applications. However, a number of important issues concerning their robust design needs to be resolved before they can be widely used. This research addresses some of those issues. In particular, it deals with: 1) Exhaustive study of the properties of signed adaptive IIR filters, with special emphasis on the development of design tools and guidelines to ensure their robust performance. 2) Design of adaptive IIR filters which are time varying. Both slow and fast time variations will be considered. 3) Development of formal methodologies for designing error filters for a range of adaptive algorithms. The resolution of the above issues will contribute to the basic understanding of issues linked to good adaptive filter performance and lead to the development of design tools for a spectrum of applications.

自适应IIR滤波器可用于许多信号处理和通信应用。然而，在它们被广泛应用之前，需要解决一些关于它们健壮性设计的重要问题。这项研究解决了其中的一些问题。特别是，它涉及：1)详尽的研究签名自适应IIR滤波器的特性，特别强调设计工具和准则的发展，以确保其鲁棒性能。2)时变自适应IIR滤波器的设计。将考虑慢时间和快时间变化。3)为一系列自适应算法设计误差滤波器的形式化方法的发展。上述问题的解决将有助于对与良好自适应滤波器性能相关的问题的基本理解，并导致一系列应用的设计工具的开发。
