Echo Cancellation I: Algorithms Simulation
Abstract
Echo cancellation system used in mobile communications is analyzed. Convergence behavior and misadjustment of several LMS algorithms are compared. The misadjustment means errors in filter weight estimation. The resulting echo suppression for discussed algorithms with simulated as well as rela speech signals is evaluated. The optional echo cancellation configuration is suggested.
