Abstract

A method for synchronization of a mobile radio receiver having a time slot structure for a radio signal is disclosed. A data stream received by the mobile radio receiver is filtered in a filter, thereby producing a decision sequence of received data as a set of maximum possible determined time slot boundaries. The decision sequence is processed in a two-step method such that, in a first method step, a subset is selected from the decision sequence and, then, in a second method step, the elements of said subset are averaged over time, with the time slot boundary which is used for synchronization being obtained as the result of this averaging process. In this case, the subset is selected using statistical characteristics of those signal sample values that are associated with a time slot boundary, and of those signal sample values which are not associated with a time slot boundary.
