摘要
本论文是进行基于位置信息的无线资源管理的研究。本论文分为两部分,第一部分着重研究无线蜂窝网络中的无线定位算法。第二部分主要研究位置信息与无线资源管理的结合。
     对于第一部分,本文先研究了基本的定位算法,并进行了性能仿真,仿真结果表明三种基本的TDOA算法中,Chan算法的性能最优,但是与TDOA/AOA混合定位算法相比,Chan算法的性能是次优的。然后深入研究了在非视距传播环境下基于TOA(Time Of Arrival,信号到达时间)的几何定位算法,提出了一种新的算法,把距离几何定位引入到基站选择中。仿真表明,这种算法能够有效的抑制NLOS误差,提高定位精度。
     第二部分的研究工作包括两块内容。一、首先研究了中继管理。对单中继系统中的资源管理进行了研究与仿真,提出了集中式调度与分布式调度两种方案,并分析各自的优缺点。集中式调度的小区吞吐量略好于分布式调度;但分布式调度的边缘用户性能略好于集中式调度。在多中继系统中,中继节点就是最关键的无线资源之一,本文研究并提出了了基于位置信息的中继节点选择算法,通过仿真表明信道容量会受到候选中继节点的个数以及增益阈值的影响,同时也证明了位置信息对于中继节点选择的重要性。二、干扰协调是当前无线通信系统中一种重要的资源管理技术。如何区分中心用户和边缘用户至关重要。本文根据位置信息对用户进行分类,研究并仿真了多种干扰协调的算法,并对各算法性能进行了分析与比较。仿真表明,加入干扰协调之后,能够一定程度地提升边缘用户的性能。通过比较三种干扰协调方案,SFR方案二的小区平均频谱效率虽然没有显著提高,但极大的提高了边缘用户效率,是比较优的一种方法。
This paper mainly focused on radio resource management based on position information. It is consisted by two parts. The first part focuses on wireless location algorithm in wireless cellular networks. And the second part focuses on combination of position information and radio resource management.
     Firstly, mathematical models of some basic location algorithms are established. The advantages and performance of these algorithms is analyzed by simulation. Then, a deep research on the geometric location algorithm is done based on TOA (Time of Arrival, signal arrival time) against non-line-of-sight propagation. Then a new algorithm is proposed which introduced geometric location method into base station selection. It can mitigate the NLOS error and improve location accuracy.
     The second part includes relay management and interference coordination. Two algorithms which called centralized scheduling and localized scheduling are raised in relay management. These two algorithms are applicable in single relay scenario. The advantage and disadvantage are analyzed by simulation. Village throughput of centralized scheduling is slightly better than distributed scheduling. But the edge users'performance of distributed scheduling is slightly better than centralized scheduling. Relay is the important resource in multi-relay scenario, so the relay selection algorithm based on position information is proposed. The results show that the channel capacity will be affected by the number of candidate relay nodes and gain threshold. It is also proved by simulation that position information is important in relay selection. Interference coordination is also one of the most important resource management technologies. And how to classify cell-center users and cell edge users is critical for interference coordination. In this paper, the users are classified by position and different algorithms are studied and simulated. In the end, the performance of those algorithms is compared. The performance of the edge users is improved, when joined interference coordination. By comparing three interference coordination schemes, although area average spectrum efficiency of SFR scheme II is no significant increased, but the efficiency of edge users is greatly improved. It is proved to be a method of optimal.
