    摘要: 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.

    摘要: In a method for synchronization of a receiver to a transmitter which periodically transmits a sequence which is known in the receiver, a subset of possible synchronization times is determined in a first selection process by repeated correlation of the received signal with the known sequence and comparison of the correlation responses, as calculated for the correlations, with a threshold value. The threshold value is in this case varied adaptively as a function of at least one parameter which is measured during the correlations.

    摘要: An apparatus for readjustment of a sampling time in a radio receiver includes a means for determination of any sampling time error in a discrete-value received signal that emits a sampling time error signal. A filter arrangement is provided that includes a multi-rate filter that filters the sampling time error signal. A correction element receives the discrete-value received signal and the filtered sampling time error signal, and emits a discrete-value received signal whose timing has been corrected in accordance with the sampling time error.
