用AR模型法进行功率谱估计的各种算法比较，包括自相关法，BURG法，ARMA模型估计，PISARENCO谐波分解法(AR model method used to carry out a variety of power spectrum estimation algorithms, including the auto-correlation method, BURG Act, ARMA model is estimated, PISARENCO harmonic decomposition method)

还是不同密度的高斯噪声，可跟上一个程序作比较(Gaussian noise or different densities may be compared to a program to keep up with)

CLP Interface to LP/QP solver MEXCLP

Audio filter for Matlab How is it working? 1) Take the current samples and some previous samples (which previously had been stored) for multiplied by a factor defined. 2) Take the output values in past moments and multiply by other factors. 3) Finally, all the results of all these multiplications are added, giving an outlet to the current moment.

一种改进的基于PCNN神经网络和QPSO粒子行为的PSO的图像滤波算法，也可以较好地去除高斯噪声(Improved PCNN-based neural network and PSO behavior QPSO particle image filtering algorithm can also be better to remove Gaussian noise)

选取了民歌，古筝，摇滚和流行不同音乐，用神经网络对其进行有效分类。(Different from folk songs, guzheng, rock and pop music, using neural network to classification effectively.)

给音频加100hz正弦噪音，分别用巴特沃兹、切比雪夫、椭圆滤波器滤波，显示误差曲线(Plus 100hz noise to sound, respectively Butterworth, Chebyshev, elliptic filter filtering error curve)

针对基本无线传感器网络DV-Hop定位算法中，计算平均跳距时产生偏小误差的原因，提出了基于平均跳距修正的DV-Hop算法。改进算法中，引入信标节点个数比例、所有信标节点平均跳距的最大值以及所有信标节点平均跳距的平均值三个因子，并采用它们对平均跳距进行修正。通过Matlab软件对算法进行仿真验证，结果表明，改进后的 DV-Hop 算法有效降低了未知节点的定位误差，是一种可行的无线传感器网络节点定位解决方案。(DV-Hop localization algorithm for wireless sensor networks, we calculate the average hop distance small error of reasons, raised the DV-Hop algorithm based on the average hop distance correction. Improved algorithm, the proportion of the number of nodes, the introduction of beacons, the beacon node average maximum jump distance as well as all the beacon nodes average jump from the average of three factors, and their average hop distance correction. Matlab software simulation results show that the improved DV-Hop algorithm effectively reduce the unknown node positioning error, the solution is a viable wireless sensor network node positioning algorithm.)
