基于基扩展的快时变信道建模及仿真

The Modeling and Simulation Based on BEM Fast Time-varying Channel

针对无线通信中的快时变信道建模与评估,通过已有的信道测试参数中的部分数据,采用基扩展的方法,对信道进行建模,并根据模型评价的两个指标—模型准确度和算法复杂度,对快时变信道进行综合评价,最后给出了仿真结果.

This thesis discussed the problem of modeling and evaluation of fast time -varying channels in wireless communication .First, the concept of BEM function was adopted to build the model , using the existing channel parameters of the data in the test .Then the fast time -varying channel was evaluated according to the two indexes -the accuracy of the evaluation and the complexity of the algorithm comprehensively .Last , this the-sis presented the conclusion of the simulation .
