Abstract

본 발명은 TV 화이트 스페이스를 이용하는 무선랜 시스템의 스펙트럼 마스크 요건을 만족하도록 신호를 송신하는 방법 및 장치에 관한 것으로, 그 방법은 복수의 널 톤들을 포함하는 OFDM 심벌들을 윈도윙 처리하는 단계; 윈도윙 처리된 OFDM 심벌들을 포함하는 송신 신호에 대해 저역 통과 필터링을 수행하는 단계; 및 저역 통과 필터링된 송신 신호의 파워를 증폭시키는 단계를 포함하고, 널 톤들의 개수는 OFDM 심벌들의 FFT 크기에 따라 파워 증폭된 송신 신호가 스펙트럼 마스크 요건을 만족할 수 있도록 하는 최소값을 가진다.
