The invention relates to a self-adaptive balance method of digit TV signal channel, while the judge feedback balancer uses tap balance method in selective part, wherein said method comprises: grouping the balancer tap via group interlace; selecting effective tap from each group, to form effective group to enter balance calculation; when calculating the effective and ineffective taps, if the minimum tap signal amount is lower than the tap signal amount of ineffective group, exchanging them, refreshing the effective tap factor to track the change of signal channel; the tap factor refresh uses distant refresh method, to group the tap factor, while each mark period refreshes one group. The invention can use the rare property of multi-path signal channel, while the balance method only uses part taps, to reduce the calculation of balancer and needed calculation units. |
