    • 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.
    • 公开了一种利用多波束天线的系统,其以选择最佳波束的方式将波束切换到CDMA解调接收机。 发送路径从CDMA调制器接收业务信道输出,并将每个业务信道映射到在前向链路中具有到移动台的最佳路径的波束子集。 因此,系统操作以减少前向链路和反向链路两者的干扰,并且增加前向链路和反向链路的容量。 该系统还能够通过将前向链路和反向链路上的适当的开销信道映射到波束的不同组合来扇区来提供小区和扇区的灵活动态整形,以形成小区。 自适应阵列可以用于形成辐射图,其中可以通过调整相关阵列的信号分量的相对幅度和相位来调整扇区的方位角宽度和/或长度,该相位阵列根据根据 通信参数,例如指示该扇区上的通信信道的质量的信息,来自其他信道的干扰或在特定扇区中服务的呼叫的数量。
