A COMMUNITY ANTENNA SYSTEM IN THE CLOSED LOOP MODE AND THE METHOD THEREOF |
摘要 |
A community antenna system in the closed loop mode and the method thereof are provided, the system includes two groups of pre-weighting process modules and antenna arrays connecting in turn. The method includes the following steps: determining the pre-weighting vector and guide vector corresponding to the two antenna arrays respectively, based upon the channel information of each antenna array; using the pre-weighting vector and guide vector corresponding to the two antenna arrays to pre-weight the transmission signal and forming the two transmission signal processed by pre-weighting, the polarization mode of the two antenna array is orthogonal and that of each element in the same antenna array is same; sending the two transmission signal processed by weighting through the corresponding antenna array. |
