A control method for a high-frequency radio equipment and a high-frequency radio equipment system in spread spectrum radio data communication are provided which are interference-tolerant and can maintain transmission quality with improved receiving sensitivity. A high-frequency radio equipment system provided with, in a base station, an antenna part (3) comprised by a plurality of antennas, a radio part (1) for amplifying a received signal, band-limiting and down-converting it to an intermediate frequency, a signal processing part (2) for carrier-demodulating the signal inputted from the radio part (1), demodulating the signal which was despread-spectrum processed and synchronized and decoding the received data, an antenna control part (5) for determining a code error rate for the received data inputted from the signal processing part (2), forming an appropriate antenna pattern based on the error rate and outputting a signal for controlling an antenna switching part (4) according to the information of the antenna pattern. |
