ABSTRACT:
A method for controlling antennas of a receiving device in a radio system, especially in a mobile radio system, in which at least one change is made using a frequency hopping method between a number of transmission frequencies that are provided for the transmission of radio signals. A table is formed with data relating to the reception quality of each antenna. This data is evaluated on each change to the transmission frequency, and one of the antennas is selected as a function of the result of the evaluation. The method is especially suitable for use in systems using slow frequency hopping methods (slow frequency hopping systems), such as bluetooth or WDCT systems.
