Abstract: PURPOSE: A multi-user detector of hybrid type is provided to extend number of subscriber in each system and to improve efficiency of the detector. CONSTITUTION: A descending sort organizer(310) receives power signals and sorts the signals in the order of a largest power signal to a smallest power signal. A number decision part of user signal(320) determines SIC(Successive Interference Cancellation) detector(330). The SIC detector detects the selected power signals and a PIC(Parallel Interference Cancellation) detector detects unselected power signal. In the SIC detector; an adding filter(331) detects a largest power signal after filtering; a determine part of information value(332) decides an information value of detected signal; an interference signal generator(333) generates interference signal using decided information value, an estimated amplitude value, and user code; an interference signal cancellation device(334) does feedback to the adding filter(331) after deleting the interference signal from the user signal. In the PIC detector; the unselected signals are matched and filtered in a matching filter bank(341); a amplitude estimator(342) presupposes the amplitude of user signal by multiplying the filtered signal and estimated amplitude; a signal proliferate device(343) spreads the estimated signal; a partial adder(344) generates interface signal; a matching filter(346) matches and filters the signal after canceling the interference signal using an interference signal cancellation device; a determine part of information(347) decides information value of filtered signal.

Abstract: 본 발명에 따르면, 단일 페이서(single facer)의 파형 성형 닙(corrugating nip)의 래버린스(labyrinth) 경로는 종래의 직경이 큰 파형 성형 롤(corrugating roll) 및 지지 롤 장치(backing roll arrangement) 사이에 포획된 직경이 작은 파형 성형 롤을 이용함으로써 대체로 감소된다.  직경이 작은 파형 성형 롤은 파형 성형 하중이 걸릴 때의 휨(bending)을 방지하도록 포획된다.  이러한 골판지 제조기(corrugator)는 직경이 큰 한 쌍의 파형 성형 롤의 특징인 역효과를 나타내는 래버린스 경로 및 웨브 인장의 증가 없이 고속으로 동작될 수 있다.
