已知消息信号为一个长度为8的二进制序列；载波频率为 ，采样频率为4KHz。编程实现一种调制、传输、滤波和解调过程。(Known message signal is a binary sequence with a length of 8 the carrier frequency, the sampling frequency of 4KHz. Programming a modulation, transmission, filtering, and demodulation process.)

中央大学的hht变换程序，需要下载tbf时频工具箱(Central University hht transform the program, you need to download tbf frequency toolbox)

首先对采样信号进行傅里叶变换，计算出功率谱或幅值谱，然后用功率谱或者幅值谱的数据，计算每一个中心频率的带宽内数据的平均值。(Firstly, Fourier transform is applied to the sampled signal to calculate the power spectrum or amplitude spectrum, and then the average value of the data within the bandwidth of each center frequency is calculated by using the power spectrum or amplitude spectrum data.)
