| 摘 要： | 利用广播波束赋形技术实现小区覆盖优化是近来智能天线的一个研究热点,但是目前的研究主要集中在65°、90°等常见广播波束赋形应用上。首先介绍了智能天线广播波束赋形的基本方法,在此基础上总结了有特殊广播覆盖需求的几种常见场景,将其作为目标覆盖分析了如何生成对应的广播波束权值,并通过实验验证了特殊广播覆盖场景下权值的赋形效果。

| Abstract: | It is a research hotspot on smart antenna to optimize cell coverage by using broadcast beam-forming technology recently.However,current research focuses on some common applications of broadcast beam-forming such as 65 ° and 90 °.This paper firstly presents the basic principle of smart antenna broadcast beam-forming,based on this,several common scenes with special broadcast coverage requirement are summarized.Then the scenes are analyzed as the target coverage to generate corresponding broadcast beam weighted values.Through the experiment the effect of beam-forming under the scenes of special broadcast coverage is proved. |
