移动无线信道特性的研究与仿真

Research and Simulation of Mobile Wireless Channel Characteristics

在移动通信系统仿真中,通常需要根据实际的应用场景模拟相应的无线信道模型。本文对常用的移动无线信道进行分类,并对4种移动无线信道在MATLAB环境下进行仿真,分析信道的频谱特性及脉冲响应,并由此得出4种无线信道对应的具体应用环境。

In the simulation of mobile communication system, it is necessary to simulate the corresponding wireless channel model according to the actuat application scenarios. This paper classifies the commonly used mobile wireless channel, simulates the four mobile wireless channels in MATLAB environment and analyzes the spectral characteris- tics and impulse response of the channel, and finds out the concrete application environment corresponding to the four kinds of wireless channels.
