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过滤器在许多信号处理和通信应用程序中都有用。 但是，在广泛使用它们之前，需要解决许多有关其强大设计的重要问题。 这项研究解决了其中一些问题。 特别是：1）详尽地研究了签名的自适应IIR过滤器的性能，并特别着重于设计工具和准则的开发，以确保其稳健的性能。 2）自适应IIR过滤器的设计，时间变化。 将考虑缓慢和快速的变化。 3）开发用于设计一系列自适应算法的正式方法论。 上述问题的解决将有助于对与良好自适应过滤性能相关的问题的基本理解，并导致为应用程序范围开发设计工具。
