使用MATLAB制作gui，有代码举例，有ppt说明(Produced using MATLAB gui, there is the code example, there ppt shows)

一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

关于高维数据降维的非线性方法ＬＬＥ代码，对学习数据降维有帮助(High dimensional data on the nonlinear dimensionality reduction methods LLE code, data dimensionality reduction in learning help)

轨迹发生器，自动生成导航轨迹，可用于导航解算。(Trajectory generator, automatically generate the navigation path can be used in navigation solution.)

说明：  有关时频分析的matlab的程序 希望对大家有所帮助(the time-frequency analysis of the procedures Matlab we hope to help)

This package is very important for WRF (Weather and Research Forecast ) installation ARWpost in ubuntu

本程序仿真在给定系统延时下的QPSK系统误码率，其中没有使用成形滤波器，考虑了相位同步和符号同步，对工程人员很有参考价值(QPSK err rate simulation)

NURBS曲线拟合 可以实现无交叉的封闭曲线拟合(NURBS curve)
