MATLAB 的 [Communications Toolbox](Communications Toolbox) 中提供了 FM 调制函数 [fmmod](Frequency modulation - MATLAB fmmod - MathWorks 中国),高斯白噪声函数 [awgn](ww2.mathworks.cn/help/c),以及 FM 解调函数 [fmdemod](Frequency demodulation - MATLAB fmdemod - MathWorks 中国),可以很方便地完成 ...
This report includes AM Coherent Demodulation with its implementation using the MATLAB software. Therefore, the paper contains Fast Fourier Transform (FFT), Amplitude Modulation (AM), and AM Coherent Demodulation topics with their theoretical meanings and their figures (plots) from the MATLAB. FFT (...
The number of operations that are available for demodulation is limited by IF multiplication and filtering. The simulation of the analyzed demodulation algorithms was carried out in the Scilab environment which is a free analogue of the Matlab environment. To explain the principle of operati...
