Abstract: The present invention relates to a method for canceling out coexistence interference in a wireless communication device and an apparatus thereof. The present invention provides a method for canceling out coexistence interference between a first communication module and a second communication module in a wireless communication device. The method comprises the steps of: estimating a channel coefficient between a first antenna and a second antenna connected to the first communication module and the second communication module, respectively; generating a compensation signal by applying an inverse channel coefficient that is an inverse value of the estimated channel coefficient, to a transmission signal transmitted through the first antenna; and canceling out the interference of a reception signal received through the second antenna by adding the compensation signal to the reception signal. The method for canceling out coexistence interference in a wireless communication device and the apparatus thereof can effectively cancel out coexistence interference by using channel information between transmission and reception antennas when a plurality of communication modules using the same communication band coexist in a wireless communication device.
