论文设计第2部分,设定一个滤波器阶数,比较观察QMF(CQF OQF)在不同量化级下的误差,编码效率等(Thesis design, Part 2, set a filter order to compare observed QMF (CQF OQF) at different level of quantization error, coding efficiency)

Two images can be fuse or merge on the basis of contrast using matlab program. this program fuses two images as well. Here in this zip folder two images with fuze program is atteching.

本程序运用PAST算法估计信号的子空间，MUSIC算法估计波达方向，实现了对信号的入射角度的实时跟踪。(The procedures used PAST algorithm estimates the signal subspace, the MUSIC algorithm to estimate DOA, real-time tracking of the incident angle of the signal.)

扩频通信系统仿真,包括调制解调，解扩全部过程的一个完整通信系统(matlab dss)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)
