Compensation method for intelligent antenna system after failure of part of channels
2006
The present invention discloses a method for compensating when part of channels in the intelligent antenna system lapses. The invention aims at the problem that the downward beam shaping capacity of the intelligent antennae will dramatically decline when a certain or a plurality of channels in the intelligent antenna system lapse. The compensating method of the invention in the intelligent antenna system when part channels lapse comprises the steps of: (1) obtaining the number of the disabled ascending descending channels, the disabled channel number and the lapse style; (2) sharing equally the business of all the user covered by the intelligent antenna system to each effective descending antenna to transmit if the lapse style is that the shaping antenna of the special channel is damaged;and choosing the channel with the maximal transmitting power in the effective descending channel or adapting the common signal channel to compensate the weight by the descending beam shaping weight if the lapse style is that the shaping antenna of the common signal channel is damaged. The invention perfects the covering of the intelligent antenna system to the small district and increases the capacity of the small district and the speech quality of the user.
