不同刚度对临界转速值得影响，也是matlab程序。有分析内容。(Different stiffness of the critical speed is worth, is also a matlab program. Tired ah)

LE算法的MATLAB源程序，大学老师亲自编辑，可直接运行，对初学matlab的朋友们很有帮助(LE algorithm MATLAB source, university teacher personally editor, can be directly run matlab for beginners helpful friends)

this code will help you to compute a ROC curve

说明：  信道估计程序,对多用户,多入射角度情况进行仿真.(channel estimation procedures, multi-user, multi angle of simulation.)

MATLAB 5.X入门与应用MATLAB 5.X entry and application(MATLAB 5.X entry and application)

data hiding in audio signal, using matlab

说明：  运动方程中的速度向量和加速度向量用位移的某种组合来表示，将微分方程组的求解问题转化为代数方程组的求解问题，并在时间区间内求得每个微小时间区间的递推公式，进而求得整个时程的反应。 中心差分法是一种显示的积分法，它基于用有限差分代替位移对时间的求导（即速度和加速度）。(Velocity vectors and acceleration vectors in motion equations are expressed by a combination of displacements. The problem of solving differential equations is transformed into the problem of solving algebraic equations. The recurrence formulas of each small time interval are obtained in the time interval, and then the response of the whole time interval is obtained. The central difference method is a display integration method, which is based on the finite difference method instead of the displacement derivative of time (i.e. velocity and acceleration).)

说明：  本文针对无线网络中的多种服务类型，对 无线网络的带宽分配和接入方式进行分析，深入分析了不同类型的网络带宽资源 分配和调度算法在运行过程中对网络性能的影响。同时，本文也针对切换服务对 无线网络带宽分配的影响情况进行了分析，对切换服务的路由重建方式进行优 化，提高网络的实际运行性能。(This paper has analyzed the bandwidth allocating process of wireless network with different services types and compared the performance of different bandwidth allocating schemes. At the same time, this paper also gives an eye to the impact brought by handoff process. We have optimized the handoff rerouting process to improve the performance when the handoff process tack place. The main work and contributions are presented in the following aspects.)

OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真(his simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. )
