PURPOSE:To suppress generation of noise by discriminating a synchronizing frame bit and an end pattern code at a receiver, and distinguishing a normal frame and an abnormal frame. CONSTITUTION:A frame 1 comprising (n+m) bits consists of a synchronizing frame bit F being one bit representing the head of the frame, an information bit D in (n-1) bits and the end pattern code P in m(m>=1) bits representing the end of the frame. Then whether a frame is a normal frame or an abnormal frame is distinguished depending whether the synchronizing frame bit F and the end pattern code P are received at the receiver side, and an information bit included in the frame of abnormal constitution is disregarded. Thus, the generation of noise from the abnormal frame is suppressed. |
