Abstract
There is an antenna diversity system for radio reception in moving vehicles which includes a receiver, and at least two antennas coupled to the receiver. These antennas transmit antenna feed signals to an antenna diversity module coupled between the receiver and the antennas. In at least one embodiment, the antenna diversity module comprises at least one evaluation circuit for evaluating an interference in a reception signal, and at least one processor for adjusting a magnitude and a phase angle of a linear combination of the antenna feed signals. The evaluation circuit reads and sends an interference indication signal to the processor to create a relatively low interference signal. Thus, the diversity module combines the antenna feed signals in an adjustable manner based on an magnitude of phase angle, to form a linear combined signal that is present at the output of the antenna diversity module as a reception signal.
