APPARATUS FOR INTERFERENCE CANCELLATION AND ANTI-JAMMING AND METHOD THEREFOR

摘要

PURPOSE: An apparatus for interference cancellation and anti-jamming is provided to eliminate all sorts of jamming signal and interference signal which are received through an adjacent terminal interference or a satellite. CONSTITUTION: A processor(310) extracts only the signal transmitted from the opponent terminal from the received signal. A jamming detecting unit(340) detects a null interval based on the predetermined threshold value and the existence of a jamming about one or more changes of an extracted signal power, an SIR(Signal to Interference Ratio), or an amplitude. A jammer signal storing unit(330) obtains jamming signal in a null period. The jammer signal storage part offers the obtained jamming signal the adaptive filter algorithm.
