AN ACTIVE ANTENNA ARRAY WITH A SINGLE COMMON CLOCK AND A METHOD FOR RELAYING A PLURALITY OF RADIO SIGNALS |
摘要 |
<p>An active antenna system for a mobile communications network and a method for relaying radio signal in the mobile communications network is disclosed. The active antenna system comprises a plurality of antenna elements for relaying radio signals at a first frequency band. The plurality of antenna elements is connected to a plurality of signal paths. A plurality of signal inputs for inputting radio signals at a second frequency band is connected to the plurality of signal paths. A plurality of first mixers in the plurality of the signal paths converts the frequency of the radio signals between the first frequency band and the second frequency band. A plurality of first local oscillators is connected to the plurality of first mixers and a single reference oscillator can be connected through a plurality of first dispersion elements to different ones of the plurality of local oscillators through a plurality of first oscillator signal paths and to a digital signal processor.</p> |
