Abstract
PURPOSE:To satisfactorily execute communication between a mobile station and a fixed station by avoiding the interference the disturbance of a signal, by setting the switching patterns of frequencies of other different fixed stations, respectively, to the same, and deflecting only a phase of the switching pattern on a time base. CONSTITUTION:An operation of a synchronization holder b7 is added to a usual frequency hopping operation, synchronization holding is lost temporarily, and thereafter, an offset is generated by an offset generator b2 by the number of times which has been determined in advance, by which a hopping signal whose 'phase' is different can be received. That is, a signal from the corresponding station can be switched successively and received. Also, by constituting the equipment so that a receiving state from plural fixed stations can be brought to an overall decision by a controller 23, a function for deciding the best station is allowed. In such a way, a mobile station 2a which has maintained communication to a fixed station 1a can be switched so as to receive a signal from other fixed stations 1b, 1c,... when it reaches a point P, therefore, detects the best fixed station and can execute communication to its fixed station.
