협력네트워크는 중계기를 이용하여 데이터를 전송함으로서 음영지역을 해소하고 가상의 다중입출력 구성을 통해 통신성능을 향상시킬 수 있다. 본 논문에서는 송신기와 중계기 사이에서는 동기변조 방식을 이용하고 중계기와 수신기 사이에서는 차등변조 방식을 이용하는 부분차등변조 방식을 적용한 협력네트워크의 성능을 중계기의 위치에 따라 분석한다. 성능분석은 송신기와 수신기사이의 직접파가 존재하는 시스템과 존재하지 않는 시스템 두 가지를 고려하는데, 직접파는 차등변조 방식을 적용한다. 또한 전체시스템이 차등변조 방식을 이용했을 경우에 중계기 위치에 따른 성능을 부분차등변조 방식과 비교한다. 시스템의 성능은 송신기와 수신기 사이의 심벌오류율을 이용한다.
