对一个一定范围内的数据进行分析,并画出直方图,程序很简单,书写不太规范,敬请谅解.(Painting histogram)

共振解调的过程如下：首先对采集到的信号进行傅里叶变换，然后利用传感器自身的谐振频率进行分析，对滤波后的信号进行包络，包络以后去除了高频部分，得到包络信号，再对改进的包络信号进一步进行低通滤波，最后对最终得到的信号进行傅立叶变换求其频谱图。共振解调的原理及其过程可以用图2 来进行表述。(The process of resonance demodulation is as follows: First, Fourier transform is performed on the collected signal, and then the resonance frequency of the sensor is used for analysis. The filtered signal is enveloped, and the high frequency part is removed after enveloping to obtain an envelope. The signal is further subjected to low-pass filtering on the improved envelope signal. Finally, the spectrum of the resulting signal is Fourier-transformed. The principle of resonant demodulation and its process can be expressed in Figure 2.)

自己编写的一维数学形态学滤波示例程序，可以直接运行(One dimensional mathematical morphology filtering procedures, can be directly run )

对8PSK完美建模，其中通过改变码元速率和载波频率，再计算相应的环路滤波器的参数，即可实现多种QPSK模型的解调，且该模型可通过SYSTEM generator进行量化，从而生成ISE能直接使用的HDL代码。(Perfect modeling of 8PSK, wherein by changing the symbol rate and carrier frequency, and calculate the corresponding parameters of the loop filter, to achieve a variety of demodulated QPSK model, and the model can be quantified by SYSTEM generator, thereby generating ISE HDL code can be used directly.)

包括调制，解调，信噪比计算，有详细的注释，这是一个好用的频偏估计算法的matlab仿真程序。( Includes the modulation, demodulation, signal to noise ratio calculation, There are detailed notes, This is a useful frequency estimation algorithm matlab simulation program.)

该程序是对扩展目标所使用的模型进行了matlab仿真，希望大家参考，指点(The program goal is to expand the model used by the matlab simulation, hope everyone reference point)
