Method Research Of Effectiveness Evaluation For Wireless Communication System

The burgeoning of wireless communication technologies in military and life, has been prompting the functional diversity and structural complexity in wireless communication systems. In order to have a better cognition, as well as research and application of the wireless communication systems, rational and effective methods must be used in system evaluation. In view of the limitations of traditional system evaluation methods, this paper takes developing an universal and comprehensive effectiveness evaluation component of wireless communication systems as the research background, while studying on effectiveness evaluation methods of the system as research purpose.The difficulties of the research contents involved in this paper are mainly reflected in the following two points: Firstly, wireless communication systems are of great diversity and differences, which leads to a heavy workload in integrated simulation system realization by modeling universal modules. Secondly, the evaluation content of wireless communication system effectiveness evaluation based on computer simulation must be consistent with the user requirements to the system. Meanwhile, the simulation results should be of high credibility. To solve these difficulties mentioned above, the major work of this paper is as follows:(1) Based on deeply study and analysis of the operational principle and structure of various wireless communication systems, the overall structure models of wireless communication system effectiveness evaluation is established. The fundamental principle of simulation module structure of wireless communication system is described, as well as modeling and simulation, which provides the implementation method and foundation for wireless communication system effectiveness evaluation.(2) Based on ascertaining the effectiveness evaluation theory and evaluation process, the performance indexes of wireless communication system are analyzed. After summarizing the performance indexes, this paper extracts eight evaluation indexes and characterizes them. Then the evaluation index hierarchy of the system is established and the weight of each index is determined after comprehensive analysis. Some conclusions are presented to characterize the relationship between the effectiveness of wireless communication system and the user needs to the system. Therefrom, this paper puts forward the “performance index-system effectiveness-user needs” evaluation and analysis model.(3) The effectiveness of wireless communication system is evaluated and analyzed by combining with examples, which verifies feasibility and effectiveness of the proposal and provides a favorable reference for the ultimate realization of the universal, scalable and comprehensive effectiveness evaluation components.
