ABSTRACT:
The invention relates to a method and to a device for identifying markers in data blocks. The method is characterized in that a number of data blocks (201a201n) are received by a receiver (202) and one specific data block from the number of data blocks (201a201n) is analyzed in order to determine whether the specific data block contains a marker (203) or not. Once a data block that contains a marker (203) is identified, a full-rate signaling block (206) that is transmitted at full rate and a half-rate signaling block (207) that is transmitted at half rate are searched for markers. A predetermined reference pattern is provided for correlation that is subsequently divided into sub-ranges that in turn are correlated with a predetermined reference pattern to identify a signaling frame in the full-rate signaling blocks (206) and/or the half-rate signaling blocks (207).
