【摘要】：无线通信技术在军事和生活中的迅速发展,促使了无线通信系统的功能多样性与结构的复杂化。为了能够更好的认知、研究和运用无线通信系统,必须对系统进行合理而有效的评估。鉴于传统系统评估方法的局限性,本文以开发通用的无线通信系统效能评估构件为研究背景,研究了基于计算机仿真技术的无线通信系统的效能评估的方法。本文所涉及的研究内容的难度主要体现在以下两点:第一,无线通信系统种类繁多,系统差异性大,导致建立通用的模块来实现一体化仿真系统的工程量较大;第二,基于计算机仿真的无线通信系统效能评估,评估内容需与用户对系统的需求保持一致,且仿真评估结果必须具有较高的可信度。为了解决上述难点,本文进行了以下研究:(1)在研究了多类无线通信系统工作原理与系统结构的基础上,建立了无线通信系统效能评估总体结构模型。在模型框架下,阐述了无线通信系统仿真通用结构模块的基本原理,并进行了建模与仿真。为基于计算机仿真的无线通信系统的效能评估提供了评估实施方法,并奠定了基础。(2)在明确了效能评估的理论基础和评估流程的基础上,本文首先对无线通信系统进行了各方面性能指标的分析。在此基础上对其进行了归纳总结,提炼出了八个评估指标并予以表征,建立了无线通信系统的效能评估指标体系,综合分析并确定了各指标的权重,得到了若干结论来表征无线通信系统效能与用户对系统的需求间的关系。由此,本文提出了“性能指标—系统效能—用户需求”的评估分析模型。(3)结合实例,对无线通信系统的综合效能进行了评估与分析,验证了基于计算机仿真的无线通信系统效能评估方法的可行性与有效性。为最终实现通用、可扩展的无线通信系统效能评估构件提供了有利的参考依据。
[Abstract]:With the rapid development of wireless communication technology in military and daily life, the function and structure of wireless communication system are becoming more and more complicated. In order to better understand, research and use wireless communication systems, it is necessary to evaluate the system reasonably and effectively. In view of the limitation of traditional system evaluation methods, this paper studies the method of evaluating the effectiveness of wireless communication systems based on computer simulation technology, based on the background of developing general performance evaluation components of wireless communication systems. The difficulty of the research in this paper is mainly reflected in the following two points: first, there are many kinds of wireless communication systems, which leads to the establishment of a general module to achieve the integrated simulation system of the large amount of engineering; Secondly, the performance evaluation of wireless communication system based on computer simulation should be consistent with the users' demand for the system, and the results of simulation evaluation must be reliable. In order to solve the above difficulties, the following researches are carried out: (1) on the basis of studying the working principle and system structure of multi-class wireless communication systems, a general structural model for evaluating the effectiveness of wireless communication systems is established. In the framework of the model, the basic principle of the general architecture module of wireless communication system simulation is expounded, and the modeling and simulation are carried out. It provides an evaluation method for the effectiveness evaluation of wireless communication system based on computer simulation, and establishes the foundation. (2) on the basis of clarifying the theoretical basis and evaluation flow of effectiveness evaluation, Firstly, the performance index of wireless communication system is analyzed. On this basis, it is summarized and summarized, eight evaluation indexes are abstracted and characterized, the effectiveness evaluation index system of wireless communication system is established, and the weight of each index is comprehensively analyzed and determined. Some conclusions are obtained to characterize the relationship between the performance of wireless communication system and the user's demand for the system. Therefore, this paper presents an evaluation and analysis model of "performance Indexes-system effectiveness-user requirements". (3) combined with an example, the comprehensive effectiveness of wireless communication system is evaluated and analyzed. The feasibility and effectiveness of the effectiveness evaluation method of wireless communication system based on computer simulation are verified. It provides a useful reference for the implementation of the universal and extensible components for evaluating the effectiveness of wireless communication systems.
