PROBLEM TO BE SOLVED: To use the signals of antenna elements in longitudinal and lateral directions (circumferential direction of the same time to apply weighted summation to each of signals to be separated only by using a limited number of signal lines between adjacent antenna elements and transmit each of the separated signals to an indoor unit in a code division array antenna whose elements are placed in a planar way. SOLUTION: Weighted signals of the same time of the antenna elements arranged in a planar way and arrayed in columns and rows in longitudinal and lateral directions are sequentially delayed by timesΔTv,ΔTh, respectively. Then weighted signals are sequentially summed longitudinally by each column at the same time and then the signals summed in the longitudinal direction by each column are sequentially and laterally summed for each of signal channels to be separated. |
