PEVD of Eigenbeam Signals for Speech Enhancement

In this work, we proposed a speech enhancement algorithm based on polynomial matrix eigenvalue decomposition of eigenbeam signals. The algorithm first exploits the compact representation of spherical harmonics for microphone signals on a spherical microphone array. PEVD is then applied to the eigenbeam signals to achieve speech enhancement.
