ADAPTIVE ARRAY ANTENNA SYSTEM AND WEIGHTING FACTOR CALCULATION CONTROL METHOD

摘要

PPROBLEM TO BE SOLVED: To reduce power consumption by reducing the amount of calculation required to obtain an appropriate weighting factor. PSOLUTION: An adaptive array antenna system includes a weight calculating unit 10 for calculating a weighting factor of a received signal by adaptive control, a converging state evaluating unit 14 for evaluating a converging state of the adaptive control, and a weight calculation control unit 16 for controlling an operation of the adaptive control performed by the weight calculating unit 10, depending on the result of evaluation of the converging state.
