<p>A method and a device are provided for acquiring synchronization to a received digital signal. The signal consists of consecutive frames with a frame synchronization pattern distributed over a significant part of a frame. A number of blocks of constant length (303) are received (302) and a passage is selected (304) from the same location within each received block. A regularly occurring bit value is observed (305, 306) at a constant bit position within the selected passages. As a response to an observed regularly occurring bit value, the corresponding position in the received digital signal is used (308, 309) as a starting point, and the rest of the distributed frame synchronization pattern is located within the received digital signal. <IMAGE></p> |
