在本文中，我们提出了一种方法的情况下，混合滤波器具有AE形脉冲响应的声源的在线盲分离。我们的算法完全在频域中工作，并表现出快速收敛，由于交叉频率耦合。讨论了与运行语音在线分离相关的具体问题。该算法进行成功的分离的数字混合语音信号和信号从移动和站立的扬声器记录在消声室。1.源分离在瞬时线性叠加的情况下
In this paper, we propose a method for the on-line blind separation of sound sources in the case where the mixing filters have a AE-shaped impulse response. Our algorithm works entirely in the frequency domain and exhibits fast convergence due to cross-frequency couplings. Specific problems related to on-line separation of running speech are discussed. The algorithm performs successful separation of digitally mixed speech signals and of signals from a moving and a standing speaker recorded in an anechoic chamber. 1.
