DIRECTIVITY CONTROL SYSTEM, CONTROL DEVICE, COOPERATIVE STATION DEVICE, RECEPTION STATION DEVICE, AND METHOD OF CONTROLLING DIRECTIVITY |
摘要 |
A directivity control system includes a first reception station device which receives an interference signal and a desired signal; a cooperative station device disposed at a different place from the first reception station device, which receives a signal using an antenna; and a control device which controls the directivity of an antenna of the first reception station device, wherein the control device regards a combination of the antenna of the first reception station device and the antenna of the cooperative station device as one array antenna, and calculates a sum, using a weight, of a received signal received using the antenna of the first reception station device and a received signal received using the antenna of the cooperative station device to compose a directivity pattern having a null in an arrival direction of the interference signal in the array antenna.
