目前，自适应智能天线技术已经成功的运用于商用 TDD系统(PHS, WLL)等，使网络的容量及小区的覆盖范围成数倍的提高。近年来，随着自适应智能天线技术的日趋完善，它在FDD系统中的应用也越来越被人们所重视，尤其在即将到来的第三代移动通信系统中, FDD系统将成为主流，如何更
At present, adaptive smart antenna technology has been successfully applied to commercial TDD systems (PHS, WLL), etc., so that the capacity of the network and the coverage of the cell are several times higher. In recent years, with the increasingly perfect adaptive smart antenna technology, its application in the FDD system is also paid more and more attention, especially in the upcoming third generation mobile communication system, FDD system will become the mainstream, how more
