中文说明：是基于matlab环境下对信号的调制与解调和误码率的分析，以及硬件实验与理论仿真实验的比较。方法是通过matlab软件进行数学建模软件编程使模拟仿真成功，而硬件实验是利用现有实验设备进行实验分析
English Description：
Is based on the signal modulation and demodulation and bit error rate analysis based on MATLAB environment, as well as the comparison of hardware experiment and theoretical simulation experiment. The method is to make the mathematical modeling software programming by MATLAB software to make the simulation successful, and the hardware experiment is to use the existing experimental equipment to carry on the experiment analysis.
