| 1. A method for synchronization of a mobile radio receiver having a time slot structure for a radio signal by finding a specific
time slot boundary, which is received from a base station, comprising:
receiving a data stream at the mobile radio receiver;
filtering the data stream, thereby resulting a decision sequence of values associated with the received data as a set of possible
time slot boundaries; and
processing the decision sequence further, the processing comprising:
selecting a subset of the decision sequence values using statistical characteristics of signal sample values that are associated
with one of the time slot boundaries, and signal sample values that are not associated with one of the time slot boundaries;
and
averaging the elements of the associated sample values of the subset over time, wherein the specific time slot boundary is
obtained as a result of the averaging.
