Proportionate NLMS with orthogonal correction factors for stereophonic acoustic echo cancellation

This paper presents an improved algorithm for stereophonic acoustic echo cancellation using proportionate normalized LMS algorithm with orthogonal correction factors (PNLMS-OCF). The convergence rate of improved algorithm and computational complexity are then analyzed.
