kalman filter kalman滤波及其应用

说明：  本程序适用于解决优化问题，达到某些问题的优化目标。(This procedure applies to solve the optimization problem, the optimization problem to achieve certain goals.)

无功优化的最优潮流程序，可以自行替换ieee数据(Optimal Power Flow)

子空间辨识,经典的英文版论文，学习状态子空间必备基础，包含算法和证明(Subspace Identification for Linear Systems：Theory- Implementation-Application)

说明：  多光谱和全色图像融合,对研究很有用，其中包含了很多子函数都可以调用(remote sensing fusion)

2*2 Alamouti space-time coding use MATLAB

通过仿真得到 信号误码率与信噪比的关 系, 从而为实际中 调制和解调 系统设计提供一定的理论依据。 同时 , 通过仿真技术的探讨 , 以期能为 专业教学改革提供一些新的思路(Received signal through the simulation bit error rate and SNR, in order to practice the design of modulation and demodulation system to provide a theoretical basis. At the same time, the adoption of simulation technology with a view to a professional teaching reform to provide some new ideas)

QPSK调制代码,高斯和瑞丽衰落信道后的信号波形(QPSK　Modulation)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)
