Signal subspace approach for speech enhancement in nonstationary noises


In this paper, we propose a speech enhancement algorithm that is based on signal subspace approach (SSA) combined with RL noise estimation for nonstationary noises. A signal/noise Karhunen-Loeve transform (SNK) is used to implement signal subspace decomposition for noisy speech signal. RL noise estimation is used for adaptive estimates over time for… (More)
