Abstract:
A mobile communication system comprising:an antenna of a base station for performing a directivity control of an adaptive antenna in a signal reception of the base station to obtain a radiation characteristic of the antenna in which a main beam is directed in a desired signal coming direction and in which a directivity in a direction of an interference wave source is set to null; and an antenna of a mobile station for performing the directivity control of the adaptive antenna in a signal reception of the mobile station to obtain a radiation characteristic of the antenna of the mobile station in which a main beam is directed in a desired signal coming direction and in which a directivity in a direction of the interference wave source is set to null, wherein the directivity control of the adaptive antenna is not performed for the antenna of the base station when signal transmission is performed from the antenna of the base station.
