Adaptive Filter Algorithms
by MultiDSP Inc.

Software Overview

MultiDSP's Adaptive Signal Processing (ASP) is a most efficient and easy-to-use software.  It 
contains 21 different adaptive filter algorithms: five LMSs, three lattice LMSs, three transversal 
fast Kalmans, three fast a posteriori error sequential techniques (FAEST), and four QR rotations. 
It supports four different design applications: Prediction, Modeling, Multi-Channel, and 
Multi-Dimension. Each software module can be applied to a specific application.
