不采用自适应算法的智能天线系统

Smart Antenna without Employing Adaptive Algorithm

本文提出了一种基于等旁瓣针状波束方向图的智能天线为了与采用自适应算法的智能无线进行对比，本文分别模拟了这两种不同智能天线用于CDMA系统时的扩容能力模拟结果表明，在CDMA系统中无需采用自适应算法，只需用等旁瓣外状波束智能天线，就可以达到与自适应智能天线相似的扩容性能等旁瓣针状波束智能无线的优点是：无需迭代、响应速度快。

A smart antenna bed on equal side-lobe Pencil patterns was proposed in this Paper. For comparing withsmart antennas which employ adaptive algorithm, the capacity enhancement of both smart antennas in CDMA system is evaluated. The simulation result show that the adaptive algorithm das not have to be employed. Smart antennas with equal sidelobe pencil patterns has almost the same capacity enhancement Performance. Merits of equal side-lobe pencil Pattern smart antennas are without iteration, faster response and better robustnase.
