ASPT-2.1 Release Notes

We are pleased to announce the release of the Adaptive Signal Processing Toolbox Version 2.1 for Matlab (ASPT-2.1). The new release improves and expands the previous ASPT-2.0 release in many fronts. Besides bug fixes, execution speed enhancement for many algorithms, improved and reorganized documentation, the new release adds 15 new adaptive algorithms. The new routines expand the scope of the toolbox to cover nonlinear adaptive filters and add many new high performance adaptive algorithms. The newly added algorithms include routines implementing

Fast transversal filters
Data reusing filters
Block processing filters
Recursive least squares filters with error feedback
Variable forgetting factor recursive least squares filters
Fault tolerant filters
Second order Volterra nonlinear filters
