Adaptive filters in Matlab: from novice to expert

Adaptive filters are ubiquitous tools for numerous real-world scientific and industrial applications. Many educators and practitioners employ the Matlab® technical computing environment to implement and study adaptive filters. This paper describes the design and implementation issues regarding a recently-developed set of comprehensive Matlab adaptive FIR filtering tools. In addition to a complete suite of algorithms, the tool set includes analysis functions that enable users to quickly characterize the average performance of selected algorithms when limited data are available. We provide execution speed comparisons for algorithm families to guide users in algorithm selection when Matlab execution time is most critical.
