摘要： Disclosed is a system utilizing a multi-beam antenna that switches the beams to a CDMA demodulation receiver in such a way that the best beams are selected. The transmit path takes the traffic channel outputs from the CDMA modulators and maps each traffic channel to the subset of beams that have the best path to the mobile in the forward link. Accordingly, the system operates to reduce interference on both the forward and reverse links, as well as to increase the capacity of both the forward and reverse links. The system also is capable of providing flexible dynamic shaping of the cell and the sectors by mapping the appropriate overhead channels on the forward link and the reverse link in different combinations of beams to sectors in order to shape the cell. Adaptive arrays may be utilized to form radiation patterns, for which the azimuthal width and/or length of a sector may be adjusted by way of adjustments of the relative amplitude and phase of signal components of signals at antennas of a phased array adaptively controlled according to communication parameters such as information indicating the quality of the communication channel on that sector, interference from other channels or the number of calls serviced in particular sectors.

摘要： A system and method are disclosed for dynamically sizing sectors of a multi-sectored radiation pattern. The disclosed invention teaches the use of multiple narrow beams composited to form a radiation pattern. Signals associated with each such narrow beam may be provided to inputs of a scan receiver or signaling radio which inputs are associated with a particular sector of the radiation pattern. The number of narrow beam signals provided inputs associated with a particular sector defines the azimuthal width of that sector. By altering the number of narrow beam signals provided each such input, the azimuthal width of the sectors may be adjusted. The disclosed invention also teaches the use of attenuators in the signal path between the narrow beams and the scan receiver or signalling radio. By adjusting these attenuators, the effective length of the sectors may be adjusted.
