This paper describes a technique to ghosts cancellation without a Ghost Cancellation Reference signal. The existing vertical edges in TV image are used to estimate the channel characteristics. With the estimating results, the coefficients of the equalizer are updated. In this paper, a method to speed up the convergence is given. The equalizer structure for cancelling all kinds of ghosts is discussed too. A new improved solution is achieved by interpreting the TV synchronisation signal as a genuine edge.

Equalizing a mobile TV channel requires a readjustment of the equalizer during picture transmission due to the Doppler shifting. New approaches, like blind equalization, are presented, which are also interesting for equalizing stationary receivers.
