Abstract
PURPOSE:To enable the simplicity and low cost for the diversity unit, by selecting the phase of the reception wave of each antenna before the synthesization with a suitable quantity, when the reception waves of a plural number of antennas are synthesized and detected and the synthesized level is less than the selecting level.
