说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

说明：  此程序用matlab编码，可以生成随机骨料，适用于有限元分析。。。。(This program is progressed by matlab, which can generate the concretebone. It can be used in finte element analysis.)

实现PAM8，并进行误码率分析，PAM比特流通过随机数产生(Achieve PAM8, and the bit error rate analysis, PAM random number generator bit stream)

说明：  对三路单音信号合成模拟话音信号进行PCM编码，并采用BPSK调制，通过AWGN信道，接收端采用BPSK相干解调和PCM译码，恢复原模拟信号(PCM coding is used to synthesize analog voice signals from three monotone signals. BPSK modulation is used to restore the original analog signals through AWGN channel. BPSK coherent demodulation and PCM decoding are used at the receiving end.)

用interrupt控制两个电机，要求可以随意改变任意一个的速度(use interrupt)

纹理贴图，一个花瓶的演示图，用的matlab，适合初学者。(texture mapping)

三相同步发电机通过整流器输出交流电,供给负载发电，测量输出电压变化波形(Three phase synchronous generator output DCcurrent by rectifier,measure the output voltage waveform)

讲解如何画3D的极坐标图形！有M文件和说明！(Explain how to draw 3D polar coordinate graphics! M-file and instructions!)

为基于DSP控制的手动机器人扩充PS/2手柄的源码(DSP-based control of robot hand extended PS/2 source handle)

对时域信号精准的实现角域重采样,并进行阶次傅里叶变换,且代码注释较多,适合新手(The angle domain resampling is precisely realized for the time domain signal, and the order Fourier transform is carried out, and the code annotation is more, suitable for the novice.)
