摘要

PPROBLEM TO BE SOLVED: To enhance the accuracy of a weight coefficient with respect to a demodulated data signal by using an unknown signal radio-transmitted adjacent to the demodulated data signal so as to optimally calculate the weight coefficient of an array antenna. PSOLUTION: A transmission frame of a wireless signal received by the array antenna comprising a plurality of antenna elements ANT1 to ANTN includes a MAC1 signal, a known pilot signal, a MAC2 signal, and a demodulated data signal in this order, the MAC1, 2 signals are configured with same unknown signals, and a weight coefficient calculation apparatus is provided with: an adaptive control circuit 6b for applying adaptive control to the received signal so as to minimize an error between the received signal and a reference signal for calculating the weight coefficient; and a reference signal providing means for generating the reference signal corresponding to the MAC2 signal on the basis of the MAC1 signal and providing the reference signal to the adaptive control circuit 6b for calculating the weight coefficient based on the MAC2 signal.
