Abstract
In an antenna diversity base station of a DECT cordless telephone, at least one antenna change is carried out, for example on the basis of field strength measurements (FSM1, FSM2), in order to improve the "antenna diversity" during the reception of a DECT radio message, for example of a synchronization initiation word (E-SEW) of a synchronization field (SYF) to the DECT standard. As a result of the fact that the antenna change takes place during the reception of the synchronization initiation word (E-SEW), both optimum "antenna diversity" and interference-free transmission of wanted information contained in the radio message are possible in each transmission time slot of the DECT radio message.
