<P>PROBLEM TO BE SOLVED: To allow an inexpensive linear transmission amplifier with a small dynamic range to be used. <P>SOLUTION: A method includes: selecting a prescribed number of distributed antennas; calculating a 2D-WF weight with total transmission power limitation; generating a transmission signal to be transmitted from each distributed antenna; calculating instantaneous peak power (S3); and comparing it with allowable peak power (permissible value) (S4). If there is a distributed antenna whose instantaneous peak power exceeds allowable peak transmission power, its signal waveform is scaled down so that its peak power equals to the allowable peak power, and difference with the original total transmission power is allocated to other distributed antennas as surplus power (S5a). This is repeated until peak transmission power of all distributed antennas joining transmission will become equal to or less than the allowable peak transmission power. On the other hand, one new distributed antenna may be added to allocate the surplus power to it (S8). <P>COPYRIGHT: (C)2012,JPO&INPIT |
