Abstract

본 발명은 주파수중첩(folding)방식으로 신호처리를 하는 시스템에 있어서, 인코더(Encoder)와 디코더(Decoder)에서의 샘플링위치를 일치시키기 위해서 상관성 있는 패턴을 반복하여 발생함으로써, 디코더에서 정확한 포인트를 샘플링할 수 있게 하는 ID패턴(IDentification pattern)삽입방법에 관한 것으로, 기록매체나 전송 채널의 대역폭을 고려하여 패턴의 엣지에 적절한 기울기를 인가해 주는 것을 특징으로 한다. 따라서, 고주파부분에서의 패턴의 왜곡을 방지할 수 있어, 디코더에서 정확한 위상에서 샘플링할 수 있으므로, 정확한 신호의 복원이 가능하다.According to the present invention, in a system for processing a signal by a frequency folding method, a precise pattern is sampled at a decoder by repeatedly generating a correlated pattern so as to match a sampling position at an encoder and a decoder. The present invention relates to a method of inserting an ID pattern, wherein an appropriate slope is applied to an edge of a pattern in consideration of a bandwidth of a recording medium or a transmission channel. Therefore, the distortion of the pattern in the high frequency portion can be prevented and the decoder can sample at the correct phase, so that the correct signal can be restored.
