The object of the present invention is to provide a radio communication system and a mobile station for the system that increase the number of mobile stations that can connect to the same frequency resource while maintaining communication quality.In order to achieve the stated object, the mobile station is notified of unique word information, which is different for each mobile station, from a radio base station through the control channel, stores the information in a UW information storage unit, modulates a synchronization code which includes the information into a reference signal through a re-modulation signal, and stores the result in a memory. When transmission and reception are performed on a link channel, a weight calculation unit forms directivity in the direction of the radio base station using the reference signal. By performing directivity control in the mobile station, interference signals radiated to other wireless zones are reduced while interference signals from other wireless zones are eliminated, therefore the space between re-use of frequencies can be shortened, and the number of mobile stations that can be accommodated in the same frequency resource can be increased.
