自适应阵列天线区域覆盖算法研究

内容简介：文章分析了自适应阵列天线信号空间分割原理，介绍了自适应阵列天线区域资源传统分配算法：固定式区域资源分配算法和最大最小区域资源分配算法。针对自适应阵列天线区域资源传统分配算法存在的问题，提出了基于最小标准差的区域资源改进分配算法，并介绍了其区域资源分配原理和计算方法。通过对以上三种区域资源分配算法的通话阻塞率仿真可知，最小标准差区域资源分配算法相对于区域资源传统分配算法可降低通话阻塞率，负载平衡效果最好。

Abstract：This paper analyzes the space partitio theory of adaptive array antenna signals, introduces the traditional resource allocation algorithm of the adaptive array antenna area.resource fixed regional resource allocation algorithm and maximum and minimum regional resource allocation algorithm. Concerning prob- lems existing in the traditional resource allocation algorithm of the adaptive array antenna area, the alloca- tion algorithm for improvement of regional resources based on minimum standhrd deviation is put forward, and the principles of its regional resource allocation and calculation methods are introduced. Through simu- lation of call blocking rates for these three regional resource allocation algorithms, we can know that, the regional resource allocation algorithm of minimum standard deviation can reduce the call blocking rate com- pared with the traditional regional resource allocation algorithm, and the result in load balancing is best.
