| titleOfInvention | Method, apparatus, base station, and base station site for reducing the number of feeders in an antenna diversity system |
| abstract | A method, apparatus, and system for reducing the number of feeders (2, 3) between antenna diversity configurations (10, 11, 12, 13) that receive a plurality of RF signals at the same frequency as the radio base station (1). In the tower mounted amplifier (45), individual RF signals from some or all of the plurality of antennas are frequency converted to intermediate frequency (IF) signals of different intermediate frequencies, which are combined and It is transferred to the radio base station with a small number of feeders. In the radio base station, the combined signal is divided into individual signals, and IF signals are frequency-converted between these signals into signals suitable for diversity processing. |
