Summary:The present invention relates to a wireless communication device to adaptively eliminate interference and an operation method thereof. According to one aspect of the technical idea of the present invention, the wireless communication device comprises: a communication circuit for transmitting and receiving signals on the basis of a plurality of antennas; a processor detecting first interference for N resource blocks (RBs) of the signal, performing a first whitening validation test for the first interference when the first interference is detected, detecting second interference on the basis of the results of the first whitening validation test when the second interference is detected, and performing a second whitening validation test for the second interference; and a whitening filter circuit for performing whitening on the results of the first whitening validation test and second whitening validation test. 본 개시의 기술적 사상의 일측면에 따른 무선 통신 장치에 있어서, 복수의 안테나에 기초하여 신호를 송수신 하기 위한 통신 회로; 상기 신호의 N개의 RB(resource block)들에 대하여 제1 간섭을 탐지하고, 상기 제1 간섭이 탐지된 경우, 상기 제1 간섭에 대한 제1 화이트닝 유효성 검사를 수행하고, 상기 제1 화이트닝 유효성 검사의 결과에 기초하여 상기 제2 간섭을 탐지하고, 상기 제2 간섭이 탐지된 경우, 상기 제2 간섭에 대한 제2 화이트닝 유효성 검사를 수행하기 위한 프로세서; 및 상기 제1 화이트닝 유효성 검사 및 상기 제2 화이트닝 유효성 검사의 결과에 화이트닝(whitening)을 수행하기 위한 화이트닝 필터 회로를 포함하도록 구성된다.
