Abstract
A wireless communication system includes a first wireless station including antenna elements, transmission units corresponding to the antenna elements, and a transmission directivity control unit that controls transmission directivity of the antenna elements, and second wireless stations each including a reception power measurement unit that measures a reception power. The transmission directivity control unit determines the transmission directivity of each of the antenna elements so that a signal does not reach a particular second wireless station among the second wireless stations. The transmission units generate wireless signals using the transmission directivity. The antenna elements transmit the generated wireless signals. The reception power measurement unit measures the reception power in a period that is set so that a signal does not reach the particular second wireless station by using the directivity, and detect the presence or absence of interference caused by the low accuracy of channel information.
