相位编码脉冲压缩雷达的多普勒补偿算法，实现对信号的补充(Phase-coded pulse compression radar Doppler compensation algorithm, the realization of the signal added)

该程序产生MSK和GMSK复基带信号，并在同一图中作出二者的功率谱，对处理实际信号时非常有帮助(The complex base signals of MSK and GMSK are produced, respectively. The power spectral density of the two signals are darwn in the same figure, which really helps for pratical signal processing)

通过自动阈值选择方法实现图像二值化。初始阈值T是图像均值；T把图像直方图分成R1和R2两个区域；计算R1和R2均值u1和u2，选择u1和u2均值作新的阈值；重复以上步骤直到T值基本不变。(Automatic Threshold Selection；)

JITTERBUG 是一个用来仿真线性控制系统的Matlab工具箱。通过JITTERBUG，我们能得到延时、数据丢失对系统的性能影响。同时，这个工具箱还能计算控制系统中信号的谱密度。(JITTERBUG [Lincoln and Cervin, 2002] is a MATLAB-based toolbox that allows the computation of a quadratic performance criterion for a linear control system under various timing conditions. Using the toolbox, one can easily and quickly assert how sensitive a control system is to delay, jitter, lost samples, etc., without resorting to simulation. The tool is quite general and can also be used to investigate jitter-compensating controllers, aperiodic controllers, and multi-rate controllers. As an additional feature, it is also possible to compute the spectral density of the signals in the control system. The main contribution of the toolbox, which is built on well-known theory (LQG theory and jump linear systems), is to make it easy to apply this type of stochastic analysis to a wide range of problems.)
