发明名称 Methods and apparatus for blind separation of delayed and filtered sources
摘要 A method of recovering source signals from an equal number of mixed signals including components of the source signals. Channel one and two mixed signals are multiplied by channel one and two adaptive weights to produce channel one and two product signals, respectively. A channel one filtered feedback signal is generated from a channel two approximation signal and a channel two filtered feedback signal is generated from a channel one approximation signal. The channel one filtered feedback signal is added to the channel one product signal to produce the channel one approximation signal and the channel two filtered feedback signal is added to the channel two product signal to produce the channel two approximation signal. A nonlinear function is applied to the approximation signals to produce output signals. The adaptive weights and the filtered feedback signals are adjusted to maximize entropy of the output signals.
