ABSTRACT:
A method for synchronizing a receiver for a convolutionally coded reception signal having a sequence of received data symbols includes decoding the convolutionally coded reception signal by means of a Viterbi decoder that calculates a minimum metric signal sequence. The metric signal sequence is then compared with an adjustable threshold value. If metric signal exceeds the threshold value too frequently during a predetermined time period, at least one received data symbol is discarded.
