Abstract

A radio system for the reception of broadcast signals is provided that includes two antennas picking up radio signals and two signal receivers receiving the radio signals, the two antennas and the two receivers operating in diversity operating modes. The radio system further includes an antenna switching unit for creating a connection between the receivers and the antennas and a control unit for controlling the antenna switching unit and selecting the operating mode according to predetermined diversity control criterion.

Claims

1. A radio system for receiving broadcast signals, the radio system comprising:

at least two antennas picking up radio signals;

at least two signal receivers receiving the radio signals, where the two antennas and the two receivers operate in diversity operating modes;

an antenna switching unit for building a connection between the at least two receivers and the at least two antennas; and

a control unit for controlling the antenna switching unit and selecting the operating mode according to a predetermined diversity control criterion.

2. A method for controlling a radio system for the reception of broadcast signals, the method comprising the following steps:

providing a first and a second antenna and a first and a second receiver, the receivers receiving the radio signals and operating in diversity operating modes;

determining a diversity control criterion; and

controlling the connection between the receivers and the antennas and selecting the operation mode in accordance with the determined criterion.
