蜂窝异构网络下的频率复用策略选择
首发时间:2013-12-06
摘要:随着第三代通信技术的广泛使用和LTE((Long Term Evolution)技术的初涉市场,传统的蜂窝网络因频谱限制和路径衰落等原因无法满足人们日益增长的接入需求,使得引入其他蜂窝通信方式,以加强特定区域的覆盖的蜂窝异构网络被人们重视。为了提高系统容量,必须要采取有效的频率复用技术,良好的频率复用策略可以使蜂窝异构网络达到最佳性能。本文旨在研究以家庭基站为主要异构方式的蜂窝异构网络模型中频率复用策略选择问题,通过对多种复用策略的计算及分析,找出适合蜂窝异构网路模型的频率复用方法,为蜂窝异构网络的频率分配方案提供参考思路。

The Frequency Reuse Scheme Selection On The Heterogeneous Network
Abstract:With the wide use of the third generation communication technology and LTE ((Long Term Evolution) technology firstly stepping into the market, by the reason of spectrum limit and path fading, the traditional cellular networks can't satisfy people's increasing access requirements. Therefore, heterogeneous network draw people's attention by strengthening the coverage of certain areas. To improve the capacity of system, effective frequency reuse technologies must be taken, and good frequency reuse strategies can help heterogeneous network achieve the best performance. This paper is to research the frequency reuse strategy selection problem in heterogeneous network model which mainly treat the femtocells as the mainly heterogeneous way and find out frequency reuse methods suitable for the heterogeneous network model by the calculation and analysis of the different reuse strategies to provide a reference for the frequency allocation scheme of heterogeneous network.
Keywords: heterogeneous network frequency reuse femtocell
