Target talker enhancement in hearing devices
We describe a novel coherent modulation filtering technique for single channel target talker enhancement in the presence of interfering talkers. For this technique, we have expan...

On nonlinear transformations of stochastic variables and its application to nonlinear filtering
A class of nonlinear transformation-based filters (NLTF) for state estimation is proposed. The nonlinear transformations that can be used include first (TT1) and second (TT2) or...
