ABSTRACT:
A mobile communication system including a plurality of base stations arranged in a communication area, each emitting a radio wave inherent thereto and a mobile station moving in the communication area and communicating with respective base stations via the transmitted radio waves. There is previously stored a location correlation data group including correlation data representing correlation situations of a plurality of arriving radio waves produced by the transmitted radio waves at respective ones of a plurality of sampling locations within the communication area, the location correlation data corresponding to respective locations. Upon reception of radio waves at a current location of the mobile station, current correlation data is calculated representing correlation situations among received arriving radio waves for the respective mobile station. The location correlation data in the location correlation data group is compared with the current correlation data, and the current position of the mobile stations is determined in accordance with a result of the comparison, generating the determined current position data.
