主要针对的是电子通信系统教学中综合工具箱的开发和应用,基于仿真模型对此进行学习与讨论。采用的是一种Matlab的通信系统的综合工具箱,对卷积积分公式在分析与推导的过程中获得时变系统中的仿真模型公式,卷积积分公式是一种对线性时不变系统复包括输出与输入的关系,主要是采用TDL模型以及Matlab通过语言编程来实现。通过大量的实验表明,线性时不变系统是能够表现线性时变系统产生的频谱扩展,是以时间作为函数的输入信号,从而发生了衰减和相位旋转,在学习过程中也会得到很好的学习效果。 The main target is the development and application of the comprehensive toolbox in the teaching of electronic communication system, which is studied and discussed based on the simulation model. Using a comprehensive toolbox of Matlab communication system, the convolution integral formula in the process of analysis and derivation obtained time-varying system simulation model formula, the convolution integral formula is a linear time-invariant system complex Including the relationship between output and input, mainly through the use of TDL model and Matlab language programming to achieve. Through a large number of experiments, it is shown that the linear time-invariant system can exhibit the spectrum expansion generated by the linear time-varying system, and is the input signal with time as a function, so that the attenuation and phase rotation occur, and the learning process will be very good learning result.
