在本文中，我们提出了一种有效的算法，用于配置 UMTS 网络中的无线电基站天线并优化主公共导频信道 (CPICH) 发射功率。该算法基于禁忌搜索，并利用问题规模缩减技术的优势，使我们能够检测服务区域的最关键部分，其中覆盖丢失概率对相邻小区中天线配置的选择非常敏感。我们报告了源自里斯本市实际规划场景的测试网络的数值结果。
In this paper we propose an effective algorithm for configuring radio base station antennas in UMTS networks and optimizing the primary common pilot channel (CPICH) transmit power. The algorithm is based on tabu search and utilizes the advantage of a problem size reduction technique which allows us to detect the most critical parts of the service area where the coverage loss probability is very sensitive to the choice of antenna configuration in neighboring cells. We report numerical results for a test network originating from a realistic planning scenario for the city of Lisbon.
