Abstract
An adaptive antenna apparatus including a reception adaptive control circuit is provided. The reception adaptive control circuit adaptively controls respective received signals received by a plurality of antenna elements, and outputs the adaptively-controlled received signals as a combined received signal. A demodulator demodulates the combined received signal to a demodulated signal, and demodulates the respective received signals separately received by the respective antenna elements to demodulated signals. A controller compares signal quality of the demodulated signal of the combined received signal with signal qualities of the demodulated signals of the respective received signals separately received by the respective antenna elements, respectively, selects a demodulated signal having the highest signal quality, and controls to receive a received signal including a selected demodulated signal.
