PROBLEM TO BE SOLVED: To provide a mobile communication system for housing many mobile stations in a little channels by enabling a spatial separation of a transmission line. SOLUTION: A base station forms a multi-beam pattern for aligning different known pilot signals. A mobile station receives the beam, infers each delay profile of each pilot signal, and stores it. The base station transmits information in the same channel at optimum separate beams to each mobile station. The communicating mobile station measures the receiving signal delay profile by receiving the beam, multiplies the stored delay profile of #3 by the receiving signal delay profile received by the communicating mobile station when the optimum beam of the communicating mobile station is #3, while the station divide the beams #2, #4, being another interference, by the stored delay profile for outputting. |
