分别编写BPSK与QPSK调制解调系统的Matlab仿真程序，要求：发送滤波器与接收滤波器均为根升余弦滚降滤波器；信道噪声为加性高斯白噪声 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线比较对比(They were written BPSK and QPSK modulation and demodulation system Matlab simulation program requirements: a transmission filter and a reception filter are root raised cosine filter channel noise to draw error BPSK and QPSK modulation under additive white Gaussian noise rate and SNR graph, and compare and contrast the theoretical curve)

对一段语音信号进行预处理，加窗，求过零率，短时能量，求各种语音信号的特征参数。(For a period of speech signal pre-processing, windowing, and zero-crossing rate, short-time energy, and all kinds of speech feature parameters.)

通过采用ekf算法来实现SLAM，对比了真实值与采用算法后计算结果，说明程序的可行性。(EKF-SLAM Simulator ------------------ This simulator demonstrates a simple implementation of standard EKF-SLAM. It permits simple configuration via configfile.m to perform SLAM with various control parameters, noises, etc. Also various switches are available to choose known data-association versus gating, etc. The key file in this simulator is called ekfslam_sim.m . Type help ekfslam_sim for more information of how to use it. In addition to on-line animations, the simulator returns a data-structure of the logged state information for off-line processing. An example use of this data is shown in m-file plot_feature_loci.m , which plots the trajectories of the landmark estimates. Tim Bailey and Juan Nieto 2004. )

HCR protocol in MATLAB

说明：  matlab环境下的iris 和 sonar的数据聚类。包括GA、k-means、FCM（只有iris）。(Iris and sonar data clustering in Matlab environment. It includes GA, K-means and FCM(only for iris).)

多种信道的研究论文，尤其是cramer通道的详细研究与仿真。(Multi-channel research papers, in particular a detailed study of cramer channel and simulation.)

模糊C均值初始聚类中心的选择，供初学者参考(Fuzzy C-means clustering center of the initial choice of reference for beginners)

N-Dimensional Cardinal(Catmull-Rom) Spline Interpolation

基于alfa的当前统计模型对目标曲线进行跟踪，且跟踪效果良好(The current statistical model alfa-based target tracking curve, and good tracking)

网上复制了一个BP预测的程序自己改了一下，效果不是很好。 P 和T都是往期的数据(Online copy of a program his BP forecast changed a bit, the effect is not very good. P and T are the data to the period)
