Abstract
A multiple-antenna system for use in cellular communication and broadcasting. The multiple-antenna transmission system can be controlled, adjusted, configured, or reconfigured to produce desirable radiation beam patterns suitable for different types of applications. A signal distribution network may be provided in the multiple-antenna system. The signal distribution network is embedded in a transmitter and controls the distribution of signals to one or more antennas in accordance with application requirements. Various antenna radiation patterns suitable for different applications can be generated by reconfiguring the connections and gain settings in the signal distribution network. For example, narrow beams may be generated for use in unicast applications, whereas sector beams may be generated for use in broadcast applications. Certain techniques may be employed to manage the transition from one type of transmission mode to another type of transmission mode.
