METHOD AND APPARATUS OF REMOVING NARROWBAND INTERFERENCE SIGNAL IN DIGITAL CABLE BROADCASTING SYSTEM

摘要

PURPOSE: A narrowband interference signal removing method and an apparatus thereof are provided to stably receive a signal in an environment in which a multi-reflected wave and a narrowband interference noise coexist. CONSTITUTION: A narrowband reference signal removing unit(231) removes a narrowband interference signal of an input signal. An equalizing unit(232) is connected to the narrowband reference signal removing unit. The equalizing unit performs an equalization process about the input signal. A modulating unit(250) modulates output of the equalizing unit.
