子空间算法是语音增强中较新颖的算法，文件对该算法进行了仿真(Subspace method is relatively new in the speech enhancement algorithm, the algorithm was simulated file)

说明：  超宽带无线通信UWB（Ultra-Wideband ）仿真代码(Ultra-wideband wireless communications UWB (Ultra-Wideband) simulation code)

regulator matlab simulation PID control is ubiquitous. While simple in theory, design and implementation of PID controllers can be difficult and time consuming in practice. PID control involves several tasks that include:

采用MPI+OpenMP混合模型设计并实现光化学反应双层并行模拟算法，上层基于MPI实现节点间的原子分解并行,下层基于OpenMP实现节点内的多线程矩阵并行乘法。(With MPI+OpenMP mixed model was designed and implemented The photochemical reaction bunk parallel simulation algorithms, the upper atomic decomposition based on inter-node MPI implementations parallel, the lower based on OpenMP nodes of multithreading matrix parallel multiplication.)

This code compress the image using wavelets. Both gray scale and RGB images can be applied and some

实现bpsk信号的调制和解调，加噪声之后的解调(The modulation and demodulation of BPSK signals are realized)

说明：  针对调幅信号求包络波的问题，给出求调幅信号的包络程序(Demand for AM signal envelope wave problem, given the program seek AM signal envelope)

分析了该信号的时域、频域、倒谱，循环谱等,实现了对10个数字音的识别，包含特征值与特征向量的提取、训练样本以及最后的识别，合成孔径雷达（SAR)目标成像仿真，计算加权加速度,这个有中文注释，看得明白。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. To achieve the recognition of 10 digital sound, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Synthetic Aperture Radar (SAR) imaging simulation target, Weighted acceleration, The Chinese have a comment, understand it.)
