| Abstract |
|
We analyze the convergence behavior of the CRLS-SA algorithm for inverse filtering.
The CRLS-SA is a cascade adaptive filter based on the RLS algorithm, with each
section adapted independently based on global minimization. The subsection adaptation
results in reduced computational complexity. The rate of convergence is evaluated
based on the convergence time constant defined as the ratio of condition number
and sensitivity. The smaller the convergence time constant, the faster the structure
converges. Analysis and simulation explain and show that CRLS-SA exhibits faster
convergence than the direct form RLS adaptive filter for speech type signals.
