- ASK 변조된 캐리어 신호가 데이터 캐리어에서 클록 신호로 사용되고, 데이터의 중요도가 하나의 타임 슬롯내에서 캐리어 신호의 시프팅점의 위치에 의해 결정되는, 무선 전자기 전송 링크를 통한 단자와 휴대용 데이터 캐리어 간의 데이터 전송 방법에 있어서,하나의 시프팅점의 정보 내용이 다수의 N 비트에 상응하고, 상기 N은 2 보다 크거나 같으며, 상기 N 비트의 중요도가 하나의 타임 슬롯내에서 2N가능한 위치내의 시프팅점의 위치에 의해 결정되고,전송될 데이터에 할당된 시프팅점이 나타나지 않는 제로 타임 구간이 하나의 타임 슬롯의 시작 또는 끝에 있는 것을 특징으로 하는 방법.
- 100% ASK 변조된 캐리어 신호가 데이터 캐리어에서 클록 신호로 사용되고, 데이터의 중요도가 하나의 타임 슬롯내에서 캐리어 신호의 시프팅점의 위치에 의해 결정되며,타임 슬롯내에서 최후의 위치에 의해 결정된 데이터 중요도가 나타난 후에 통상적으로 타임 슬롯내에서 최초의 위치에 의해 결정되는 데이터 중요도가 나타날 때, 통상적으로 최초의 위치에 의해 결정된 데이터 중요도가 타임 슬롯의 어떤 위치에서도 시프팅점이 나타나지 않음으로써 결정되는,무선 전자기 전송 링크를 통한 단자와 휴대용 데이터 캐리어 간의 데이터 전송 방법에 있어서,하나의 시프팅점이 다수의 N 비트에 상응하고, 상기 N은 2 보다 크거나 같으며, 상기 N 비트의 중요도가 하나의 타임 슬롯내에서 2N가능한 위치내의 시프팅점의 위치에 의해 규정되는 것을 특징으로 하는 방법.
- 제 1항에 있어서, 하나의 타임 슬롯이 N 비트의 지속 시간을 갖는 것을 특징으로 하는 방법.
- 제 1항 내지 3항 중 어느 한 항에 있어서, 100% ASK 변조가 사용되는 것을 특징으로 하는 방법.
