基于马尔科夫链的两状态卫星移动信道模型
Markov chain based two-state satellite mobile channel model
摘要
Abstract
Considering that a single-state probability statistical model for satellite mobile channels can only describe a single channel environment, while a multiple-state model brings more parameters and more complicated simulation work, the dynamic simulation of a two-state (both the "ideal state" and the"non-ideal state") channel model under a wide-area environment was implemented with the filter method and the Markov chain method, according to the principle that the model should accurately depict the real transmission characteristics of the channel with the relative simplicity and feasibility. Based on the experimental data of the indium system measured by the Communication Research Center, Harbin Institute of Technology, the modeling parameters under three kinds of typical channel environments were fitted by using the least squares error criterion and the method of linear least squares, and the effectiveness of the model was verified.关键词
