Abstract :
To achieve fast initial gain and timing-phase adjustment in receivers for communication or storage systems using partial-response signaling, a synchronization preamble preceding user data is transmitted. A method for recognizing that synchronization has been achieved and that the preamble is being received, and for detecting the end of preamble is presented. The method is based on a maximum-likelihood test. Its efficiency is demonstrating by computing the probability of not recognizing the preamble when it is actually received and the probability of falsely recognizing the preamble when in fact user data are received
