摘要
智能天线技术是TD-SCDMA(时分同步码分多址)中的关键技术之一。在无线基站使用一个天线阵和基于基带数字信号处理技术,对基站的接受和发射波束进行自适应的赋形,可大大降低系统内的干扰,提高系统容量,大大降低发射功率并提高接收灵敏度。文中介绍了有关智能天线的概念、原理、工作过程,以及对通信性能的改善。
Smart antennas technology is one of the key technologies in TD-SCDMA （ Time Division-Synchronous Code division Multiple Access）. Radio base station can reduce materially interference in the system, expand the system capacity, lower the transmit power and improve sensibility by shaping their receives and transmit beams with an antenna array and baseband digital signal processing technology. In this text, the writer introduced the concept and principle of smart antennas and the improvation on the communication performance,
