Abstract

In data transmission, the beginning of a transmission has to be detected rapidly by the receiver. Generally speaking, when the transmission starts, at least carrier information is fed to the line, and therefore the receiver, detecting a transition from no information to carrier information occurring on the input line, should prepare itself for receiving messages. However, transient noise should not be mistaken for the beginning of transmission.
