  abstract={Dereverberation of speech signals in a hands-free scenario by inverse filtering has been research topic for several years now. However it is still a challenging problem because of the nature of common room impulse responses (RIRs), which are time-variant mixed phase systems having a large number of zeros close to or even outside the unit circle in the z-domain. In this contribution an adaptive multi-channel equalization algorithm based on a decoupled version of the modified filtered-X LMS (mFxLMS) will be derived in the partitioned frequency domain. This new algorithm allows for fast convergence, computational efficient implementation and a low system delay under realistic conditions such as high ambient noise and imperfect RIR estimates.
