Abstract

본 발명은 디지털 고주파 처리 기술을 이용한 근거리 무선 신호 송/수신장치 및 방법에 관한 것으로, 송신하고자 하는 근거리 무선 신호를 생성하고, 생성된 근거리 무선 신호를 주파수 확산하여 기저대역 신호를 생성하면 생성된 근거리 무선 신호의 기저대역 신호를 위상 정보로 변환하고 극변조기에서 위상 정보를 고주파신호로 변환하여 이를 송신하고, 외부로부터 고주파신호가 수신되면 중간 주파수신호를 검출하고, 검출된 중간 주파수신호로부터 영교차 신호를 검출한 후, 검출된 영교차 신호를 디지털 신호로 변환하고, 변환된 디지털 신호를 처리 가능한 신호인 근거리 무선 신호로 변환하여 처리한다. 본 발명에 따르면, AD/DA 컨버터를 극변조기와 ZXD로 대체하여 근거리 무선 신호 송/수신장치의 저전력 설계를 수행할 수 있고, 칩 사이즈를 감소할 수 있으며, 가격을 절감할 수 있는 효과가 있다.
