纯ofdm仿真代码，QAM调制，有注释，可运行(Pure ofdm simulation code, QAM modulation, with annotations, can run)

说明：  滤波器的设计及仿真(滤波器参数的选择及类型的选择等matlab源代码)(creating filter )

integrated video navigation field matlab code

用于产生多相编码序列P1码以及对产生的码字进行匹配脉压(generate P1 code and let the code throngh the matched filter)

粗糙集matlab源码，简短方便。特别适合初学者使用。注释详细。(Rough set matlab source code, a short and easy. Particularly suitable for beginners to use. Notes in detail.)

自己写的频率谱细化程序，应用了两种方法实现，经过测试效果不错，拿来和大家分享。(there are two programs that make the Zoom_fft come true.)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)
