Abstract: The present invention provides a method and system for mitigating fading and/or poor reception at a receiver. The receiver includes an antenna diversity mechanism which can be operated in a variety of antenna configurations each of which can provide different reception characteristics . The receiver evaluates the reception quality of the radio signal with the antenna in a first configuration and with the antenna in at least a second configuration and selects the antenna configuration that has the best evaluated reception for use until a subsequent iteration, when the process i s repeated. The antenna configurations can correspond to configurations wherei n reception is favored in different directions or to configurations wherein different antennas are selected, each antenna being spaced from each other antenna. The method can also improve the reception of a signal transmitted b y selecting an antenna configuration for transmissions which provides improved reception quality at the destination receiver.
