Claims (5)
- 입력단을 통해 입력되는 디지탈 데이타에 무질서도를 제공하기 위하여 스크램블링하는 단계; 상기 스크램블링된 디지탈 데이타를 길쌈 부호를 사용하여 부호화하는 단계; 및 상기 부호화된 디지탈 데이타를 변조하여 전송 채널을 통해 수신단으로 전송하는 단계를 구비하는 길쌈부호를 이용한 디지탈 통신방법에 있어서, 상기 부호화단계는 상기 길쌈 부호화되는 디지탈 데이타가 'ALL ZERO' 계열일 때 수렴되는 길쌈 부호와, 'ALL ONE' 계열일 때 수렴되는 길쌈 부호 사이에서 코드워드 교환이 이루어지는 단계를 더 구비하여, 길쌈 부호화 결과에 따라 디지탈 데이타의 코드워드를 선택적으로 교환함으로써 상기 디지탈 데이타를 랜덤화시키는 것을 특징으로 하는 디지탈 통신방법.
- 스크램블러, 길쌈 부호화기, 인터리이버와 변조기로 구성되는 송신단과, 복조기, 디인터리이버, 길쌈 복호화기와 디스크램블러로 구성되는 수신단을 구비한 디지탈 통신장치에 있어서, 상기 송신단의 길쌈 부호화기와 인터리이버 사이에 위치하며, 상기 길쌈 부호화기에서 출력되는 디지탈 데이타의 코드워드를 소정의 제어신호에 의해 교환하거나 통과시키기 위한 코드워드 교환부; 및 상기 수신단의 디인터리이버와 길쌈 복호화기 사이에 위치하며, 상기 제어신호에 의해 상기 코드워드 교환부의 역과정을 수행하기 위한 코드워드 역교환부를 포함하는 것을 특징으로 하는 디지탈 통신장치.
- 제2항에 있어서, 상기 코드워드 교환부에서는 상기 길쌈 부호화기에 입력되는 디지탈 데이타가 'ALL ZERO' 계열일 때 수렴되는 길쌈 부호와, 'ALL ONE' 계열일 때 수렴되는 길쌈 부호 사이에서 코드워드 교환이 이루어지는 것을 특징으로 하는 디지탈 통신장치.
- 제2항에 있어서, 상기 코드워드 교환부에서 상기 길쌈 부호화기의 출력데이타의 코드워드 교환여부는 상기 제어신호에 의해 결정되는 것을 특징으로 하는 디지탈 통신장치.
- 제2항에 있어서, 상기 제어신호를 상기 송신단에서 상기 인터리이버의 동기데이타와 연동시켜서 사용할 경우, 상기 수신단에서 상기 디인터리이버의 동기데이타와 연동시켜서 사용하는 것을 특징으로 하는 디지탈 통신장치.
