Abstract
A method for achieving an initial synchronization and matching a receive filter of a digital receiver of a binary baseband transmission system by employing a training sequence before the transmission of useful data. The coefficients of the digital filter that is to be matched to the received signal are obtained by means of the training sequence. Character synchronization and recognition of the end of the sequence occur automatically. After the training sequence is received, an optimally matched receive filter in the receiver is made available. The method is independent of the level of the received signal within a predetermined computing accuracy and can be implemented by means of a conventional signal processor system.
