Abstract :
In order to use limited frequency resources efficiently, a single frequency network using digital on-channel repeaters (DOCR) has been studied and would be implemented. DOCR generates strong pre-echoes to ATSC DTV receivers. In this paper we propose to use the dual-feedback equalizer to combat strong pre-echoes.
