Abstract
The effects of fading on communication using a mobile telephone is reduced by switching between two or more antennas which are used to provide communication between a base station and a mobile telephone in response to a synchronization signal without arcing. The synchronization signal is generated in accordance with a signal quality measured by the mobile telephone. The synchronization signal is either transmitted back to the base station, whereupon the base station determines whether or not to switch based on the transmitted downlink signal quality, or used by the mobile phone to generate an antenna switching instruction that is transmitted back to the base station, whereupon the base station switches between the antennas in accordance with the instruction. Alternatively, the synchronization signal is generated by the base station without feedback from the mobile telephone.
