Adaptive equalizer with impulse noise protection |
摘要 |
A digital receiver receives a multi level symbol signal that includes a frame sync. An equalizer is supplied with the signal and corrects for errors that are determined to exist therein on the basis of comparing the frame sync with a known value thereof or comparing the average level of the multi level symbols to an estimated (known) value thereof. A threshold circuit is included for rejecting impulse noise in the error signal that exceeds a threshold level that is higher than the maximum symbol level in the symbol.
