Symbol Interference and Ghost Removable Equalizer and Its Ghost Position Determination Method

摘要

The present invention relates to a symbol mutual interference and a ghost-removable equalizer and a ghost position discrimination method. In the related art, the symbol reciprocal interference (ISI) and the ghost are removed. There is a problem that can not be removed. Accordingly, the present invention configures a tap update and equalizer 210 for determining the presence or absence of ghosts from an input signal, determining its position in the presence of ghosts, and removing symbolic interference and ghosts using an initial tap coefficient loaded. The initial tap coefficient is set according to the type of ghost to remove various ghosts to increase the adaptability to various ghosts.
