Abstract: 본 발명은 무선 주파수(RF)를 사용하는 무선통신 시스템에 관한 것으로, 더 상세하게는 무선통신 수신에 사용되는 저잡음 증폭기와 필터에 디지털 신호처리 프로세서를 사용하여 적응 특성을 부여함으로써 수신된 신호의 안정적인 복원은 물론 좀 더 효율적인 감도 특성을 이끌어낼 수 있으며, 디지털 신호처리 프로세서를 사용하여 무선통신 수신기기를 구성하는 저잡음 증폭기와 필터에서 발생하는 비선형적인 특성을 자동으로 보상하여 협소한 선형증폭영역을 확장시켜 무선통신 수신단의 비선형왜곡을 보상시킴으로써   보다 안정적인 출력 특성을 이끌어낼 수 있도록 한, 무선통신 수신 안정화 장치 및 방법에 관한 것이다. 
     종래의 무선통신 수신장치는 저잡음 증폭기의 협소한 선형증폭영역과 필터의 비선형적인 특성으로 인하여 이들 부품의 선형특성의 정도에 따라 수신단의 성능이 좌우되고, 광대한 선형영역을 갖는 부품은 매우 고가로 판매되어 수신단의 가격이 상승하는 원인이 되었으며, 저잡음 증폭기의 경우 협소한 선형적인 증폭 특성을 가지는 대역만을 실제 증폭에 사용하므로써 증폭영역이 제한되고 효율적인 증폭기를 만들기가 어려운 문제점이 있었고, 수신단의 감도는 부품의 수명, 동작 온도 등에도 많은 영향을 받기 때문에 고감도 수신단 모듈의 구현, 유지 및 보수에 많은 시간과 비용이 요구되는 문제점이 있었다. 
     상기한 문제점을 해소하기 위하여 본 발명은, 
     안테나, 저잡음 증폭기, 필터, 믹서, 아날로그/디지털 변환기 등으로 구성된무선통신 수신장치에 있어서, 
     상기 아날로그/디지털 변환기에서 변환된 베이스밴드(baseband) 신호를 입력받아 임의로 생성한 테스트 신호와 비교, 분석하여 보정하기 위한 디지털 신호처리 프로세서와 ;

     상기 전압 제어 발진기로부터 발진된 주파수를 입력받아 캐리어 주파수 대역을 생성시키는 주파수 합성기와 ; 
     상기 주파수 합성기로부터 생성된 캐리어 주파수에 의해 상기 디지털 신호처리 프로세서로부터 입력되는 테스트 신호를 변환하여 기준 신호를 발생시키는 제 3 믹서와 ; 
     상기 제 3 믹서로부터 발생된 기준 신호를 입력받아 실제 수신되는 신호 레벨로 전력을 낮추기 위한 감쇠기 ; 및, 
     상기 디지털 신호처리 프로세서로부터 발생되는 테스트 신호에 의해 온/오프 스위칭 제어되는 스위치를 포함하여 구성함으로써, 
     스위치로 '기준단'을 선택하는 제 1 단계와 ; 
     상기 제 1 단계에서 '기준단'으로 선택된 스위치를 통하여 디지털 신호처리 프로세서에서 기준 신호를 인가하는 제 2 단계와 ; 
     상기 제 2 단계에서 인가된 기준 신호에 의해 각각의 필터 계수를 초기화하는 제 3 단계와 ; 
     상기 제 3 단계에서 각 필터 계수를 초기화 한 후, 원하는 신호 대역과 실제 수신된 신호 대역이 일치하는 가를 판별하는 제 4 단계와 ; 
     상기 제 4 단계에서 원하는 신호 대역과 실제 수신된 신호 대역이 일치하지 않는 경우, 각각의 필터 계수를 조정하는 제 5 단계와 ; 
     상기 제 4 단계에서 원하는 신호 대역과 실제 수신된 신호 대역이 일치하는 경우, 조정된 필터 계수를 결정하는 제 6 단계와 ; 
     상기 제 6 단계에서 필터 계수를 결정한 후, 스위치로 '수신단'을 선택하는 제 7 단계 ; 및, 
     상기 제 7 단계에서 스위치를 '수신단'으로 선택한 후, 시스템이 쉬는 상태인가를 판별하여 시스템이 쉬는 상태인 경우 상기 제 1 단계로 귀환하고, 반면에 시스템이 쉬는 상태가 아닌 경우 상기 제 7 단계를 반복 수행하는 제 8 단계로 이루어짐을 특징으로 한다. 
     따라서, 본 발명에 의하면 무선통신 수신단에 사용되는 저잡음 증폭기의 협소한 선형증폭영역을 확장할 수 있으며, 무선통신 수신단에 사용되는 필터의 비선형적인 특성을 극복할 수 있고, 무선통신 수신단의 비선형 왜곡이 자동으로 보정되며, 무선통신 수신단에 사용되는 부품의 수명 및 온도에 따른 수신단의 감도 변화를 교정하기가 용이하고, 무선통신 수신단 설계시 광범위의 선형동작을 신뢰할 수 없는 저가의 부품에 대한 선택의 폭이 넓어지며, 무선통신 수신단 설계시 고감도수신 모듈 구현에 많은 비용과 시간 그리고 전문적 지식이 요구되지 않고 유지 및 보수가 용이하고, 디지털 신호처리 프로세서에 의한 실시간 보정으로 인해 보다 안정적인 고감도 신호를 수신할 수 있는 효과가 있다.
