Application of QR-LS algorithm for one-channel and two-channel acoustic echo cancellation

This paper employs the fast adaptive QR-based least squares adaptive algorithm for one-channel and two-channel acoustic echo cancellation. Adaptive finite impulse response (FIR) filters are employed to model the acoustic echo paths for one channel and two channels acoustic echo paths. Simulation results conducted attest to fast and effective echo cancellation capability of QR-LS algorithm in acoustic echo cancellation applications.
