    • An adaptive antenna control method is used for a radio communication system built by a plurality of radio base stations and a plurality of terminal stations capable of communicating with the radio base stations. Each radio base station includes an adaptive antenna having a plurality of antenna elements, a distributor for generating signals to be input to the plurality of antenna elements by branching a signal of one system to be transmitted, and weighting circuits for respectively weighting transmission signals to the plurality of antenna elements. For reception by each terminal station, an interference wave power given by the transmission signal from each of the plurality of radio base stations is estimated. A weight in the adaptive antenna of each radio base station is determined to minimize a sum of square errors between reception signals and desired signals for all the radio base stations which simultaneously use the same communication channel. An adaptive antenna transmission/reception characteristic control method is also disclosed.

    • An adaptive array antenna system for stable directivity control and waveform equalization even under poor multipath environment is provided. An output of antenna elements (A1011-A101n) is weight combined (A103), and is output through automatic frequency control (A106) and fractionally spaced adaptive transversal filter (A107) which have real number weights. Weight combination (A103) is initially carried out with weights for an eigen vector beam for the maximum eigen vector of the correlation matrix Rxx of a receive signal After carrier synchronization and timing synchronization between a receive signal, and an A/D converter and a fractionally spaced transversal filter are established by the automatic frequency control and the fractionally spaced transversal filter, the weight in the weight combiner (A103) is switched to minimum mean square error (MMSE) weight. Sampling rate for A/D conversion under an eigen vector beam forming is higher than twice of that of transmission rate, with asynchronous timing to a receive signal.
