Get Function Transfer System Using Tustin / Trapezoidal / Bilineal Aproximation

grayscale decoding method

1、语音信号的采集； 2、语音信号的频谱分析； 3、数字滤波器的设计； 4、对语音信号进行滤波处理； 5、对滤波前后的语音信号频谱进行对比分析； (1, speech signal acquisition 2, the speech signal spectrum analysis 3, digital filter design 4, on the voice signal filtering processing 5, to filter the speech signal before and after a comparative analysis of the spectrum )

选择一种编码方式。在这里可以采用行编码和列编码，但经过大量的实验表明，这两种编码方式的抗干扰性能不佳(choose a coding. The trip here can be used coding and coding out, but after a lot of experiments showed that both the encoding anti-jamming performance poor)

用MATLAB实现通信原理的QAM与MSK编码。两个源码以及用到的自己编写的相关MATLAB函数分别放在相应的文件夹下。(Using MATLAB and MSK communication principle of QAM encoding. Both source and associated MATLAB functions used in their preparation were placed in the appropriate folder.)
