Abstract

16 QAM modulation and demodulation mode has the advantage of high noise tolerance and superior anti-noise performance, and it is suitable to work in the environment with large signal-to-noise ratio and band-limited value. MATLAB has the advantage in data analysis and processing, and it integrates matrix calculation, numerical analysis, scientific data visualization, modeling and simulation of nonlinear dynamic systems and some other powerful functions in an easy-to-use windows environment so that it can provide a comprehensive solution for scientific research, engineering design, and some other fields. Accordingly, a simulation method of 16QAM modulation and demodulation based on MATLAB is proposed, which can simulate the 16QAM modulation and demodulation of the randomly-chosen signal as well as get the simulation image by compiling and running the matlab program. This method can reflect the change of parameters as well as the dynamic working process of modulation and demodulation, and it can also perform the data process, waveform, and performance analysis of the image obtained in the end, which has the advantage of intuition and clarity.

基于Matlab平台的16QAM调制解调仿真方法

16 QAM调制解调方式具有高噪声容限和优越的抗噪声性能的优点，适合在信噪比大、限带值的环境下工作。MATLAB在数据分析和处理方面具有优势，它在易于使用的窗口环境中集成了矩阵计算、数值分析、科学数据可视化、非线性动态系统建模与仿真等强大功能，可以为科学研究、工程设计等领域提供全面的解决方案。据此，提出了一种基于MATLAB的16QAM调制解调仿真方法，通过编写并运行MATLAB程序，可以对随机选择的信号进行16QAM调制解调仿真，并得到仿真图像。该方法可以反映参数的变化以及调制解调的动态工作过程，还可以对最终得到的图像进行数据处理、波形和性能分析，具有直观、清晰的优点。
