Equalization of speech and audio signals using a nonlinear dynamical approach
Alexander M. Chan, HENRY K. LEUNG · IEEE Transactions on Speech and Audio Processing · 1999
We present the minimum phase space volume (MPSV) technique, a nonlinear dynamical technique for enhancing speech and audio signals corrupted by convolutional noise. The MPSV technique requires no assumptions or a priori information about the original signal, remains effective when the inverse filter order is overestimated, and significantly outperforms the LS method.
