An apparatus and method for a receiver to recognize channel numbers, skew delays, and polarities of N channels by extracting the properties of the transmitted signals are provided. Each of the N signals comprises a plurality of digital symbols with certain characteristics known to the receiver. The apparatus comprises a calculation unit, a statistic unit, and a selection unit. The calculation unit is used to compute a value for each channel according to the properties of the digital symbols captured on that particular channel within a predetermined interval. The statistic unit is used to derive a plurality of statistical values based on the values from the calculation unit. The selection unit recognizes the special property of a channel, identifies the remaining N-1 channels, compensates the skew delays, and corrects polarities.
