用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

卫星电视接收 dm500 源码，dm500 dm500(Satellite TV receiver dm500 source, dm500 dm500)

he m-file helps you o understand the generatio,transmission and reception of an ofdm signal, and also shows the effect of the channel noise and the HPA on the ofdm signal.

直流双闭环调速系统的搭建模型，采用PID控制器控制。(Double closed loop DC speed control system to build the model, using the PID controller.)

在重构相空间的基础上计算吸引子的分形维时,合适的嵌入维m和时间滞后τ的选取至关重要.在虚假邻域概念基础上,本文给出了确定m和τ的方法.较之以前的方法,此方法更准确、简单、容易理解、易实施,对较小样本数据集也可靠.最后的应用实例验证了理论的正确性.(In the reconstructed phase space based on the calculation of the fractal dimension of attractor, the appropriate embedding dimension m and time lag τ selection is essential. In a mock neighborhood based on the concept, this paper presents the method to determine m and τ. Compared with the previous methods, this method is more accurate, simple, easy to understand, easy to implement on a smaller set of sample data is also reliable. The last application example to verify the theoretical correctness.)
