the second beam former 1011 the second beam former 1011 distributes the output from the estimation pilot generator 1010 for every time slot toward the respective transmission antennas to control an amplitude and a phase with respect to each of the antenna elements while the amplitude and the phase correspond to a directional beam supplied from the estimation beam generator 1009 the above described control is carried out for every beam identification number the amplitude phase control process results which are related to all of the beam identification numbers are added to each other for every antenna element and then the added process results are transmitted to the second time division multiplexer 1012 the second time division multiplexer 1012 multiplexes the output of the first beam former 1006 and the output of the second beam former 1011 in a time division multiplexing manner for every antenna element and then transmits the time division multiplexed output to a front end fe unit 1013 for every time slot fig5 again represents an example of a time division multiplexed signal in fig5 dp 101 indicates a detection pilot data 102 indicates forward link data and pp 103 indicates an estimation pilot there is no change in the effects of this invention by arranging the pilots and the data in a temporal manner it should be noted that the present embodiment.
