    • A multi-channel blind deconvolution method for canceling interference and echo signals is provided to separate an interference signal and a separation signal to obtain the separation signal which is close to an original signal. A mixture signal acquiring unit(101) acquires a mixture signal and processes it into a format suitable for obtaining a separation filter. The mixture signal is inputted from the mixture signal acquiring unit to an interference signal canceling unit(102). The interference signal canceling unit cancels only an interference signal from the mixture signal to acquire a primary separation signal. An echo signal canceling unit(103) cancels an echo signal from the primary separation signal to acquire a final separation signal. A successive signal processing unit(104) converts a signal which has been separated by frames into the original successive signal.
    • 提供用于消除干扰和回波信号的多通道盲去卷积方法,以分离干扰信号和分离信号,以获得接近原始信号的分离信号。 混合信号获取单元(101)获取混合信号并将其处理成适于获得分离滤波器的格式。 混合信号从混合信号获取单元输入到干扰信号消除单元(102)。 干扰信号消除单元仅从混合信号中消除干扰信号以获取主分离信号。 回波信号消除单元(103)从主分离信号中消除回波信号以获得最终分离信号。 连续信号处理单元(104)将已经被帧分离的信号转换成原始的连续信号。
