A method and apparatus for separating a multi-channel mixed signal are provided. The method includes the steps of: a) transforming a temporal domain to a frequency domain by performing a discrete Fourier transform onto at least one of mixed signals inputted from an external device through multi-channel; b) estimating multi-decorrelation by calculating a plurality of cross power spectra for the mixed signal in the transformed frequency domain; c) estimating a separation coefficient of the mixed signal based on relative optimization in order to decorrelate the calculated cross power spectra, where the separation coefficient is serially updated; d) transforming the frequency domain to the temporal domain by performing an inverse discrete Fourier transform on the estimated separation coefficient in the temporal domain; and e) separating an original signal from the mixed signal by filtering the mixed signal using the separation coefficient of the transformed temporal domain.

A refrigerator has a water tank, a pump with a motor, a current detecting part, and a controller. The current detecting part detects a motor current flowing through the motor so that the current detecting part outputs control signals like a binary of high/low level according to the detected motor current. The controller turns on/off the motor according to the control signal from the current detecting part. By this refrigerator, the existence of the water in the water tank may be detected accurately.

The present invention relates to a door duct assembly for a refrigerator. In the present invention, the cold air delivered from a cold air duct of a refrigerator main body to a door 30 through a cold air communication portion 55 is discharged into a storage space through cold air vents 61 formed in a flow guide 60. The cold air communication portion 55 is formed in a door basket 40 or the flow guide 60. The door baskets 40 or the flow guide 60 is mounted on a door liner 33 defining a rear surface of the door 30. According to the present invention, there are advantages in that it is relatively easy to manufacture a door, the cold air flows uniformly in the door, the strength of the flow guide for defining a flow channel in the door is relatively increased, and dewdrops are prevented from being formed upstream of the flow channel.
