Abstract:
1. A method for resynchronization of a mobile radio receiver in the event of a changeover between two different modulation methods by which data of a data burst transmitted from a base station to the mobile radio receiver are modulated, comprising: determining synchronization information items from a first part of the data burst modulated by a first modulation method; and synchronizing the mobile radio receiver with a second part of the data burst modulated by a second modulation method using the synchronization information items determined; wherein in the reception signal path of the mobile radio receiver, in the event of the changeover between the modulation methods, a fixed temporal offset, in particular a fixed phase relationship, is provided and the information items of the fixed temporal offset and the synchronization information items of the first part are used for synchronizing the second part of the data burst.
