Study on Wireless Channel Based on Fractal Brownian Motion

介绍了分形布朗运动与无线信道中信号的关系,并运用分形布朗运动模型,基于MATLAB仿真工具,对分形布朗信道下的无线信号功率谱进行仿真分析。结果证明了分数布朗运动建模无线信道的可行性,并表明了对于不同的无线信道,可以利用检测功率方法估计其分形维数。

This paper introduces the relationship between fractal Brownian motion and the wireless channel signal. By using Fractal Brownian Motion model, we simulate and analysis Fractal Brownian channel of the wireless signal power spectrum based on MATLAB. The result shows that it is feasibility for wireless channel to use Fractional Brownian Motion model. It also shows we can use the method of inspecting power to estimate the fractal dimension for different wireless channels.
