FDTD仿真，点源为硬源，上半部分是玻璃，下半部分是空气，能观察得到电磁波的反射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor.)

用MATLAB实现采样率转换的程序，附有说明文档，包括内插和抽取，以及先内插再抽取的程序(Using MATLAB to achieve sample-rate conversion process, with documentation, including interpolation and decimation, and interpolation and then taken before the procedure)

Makes 3d scatter plot much faster than scatter3

说明：  该算法连续系统的积分分离式PID算法,用MATlab开发，能够管直接运行,当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。(The algorithm of the integral continuous system separate PID algorithm, developed using Matlab and can directly run the tube, when the control volume and settings deviation is larger, the abolition of integral action, so as not to cause too large integral role in the stability of the system lower.)

SIGMA DELTA MODULATOR

二相相移键控（BPSK）调制解调过程的MATLAB仿真实现。ASK、FSK、PSK这三种数字调制方式在抗干扰噪声能力和信号频谱利用率等方面，以相干PSK的性能最好，目前已在中、高速传输数据时得到广泛应用。(Binary phase shift keying (BPSK) modulation and demodulation process, MATLAB Simulation. ASK, FSK, PSK modulation in the three digital noise interference and signal spectrum efficiency, etc., to the best performance of coherent PSK, is now in the middle and high-speed transmission data are widely used.)

说明：  程序运用l_curve法 对一病态问题进行求解 (procedures for the use of a law l_curve pathological problem solving)

快速可靠的GPS (全球定位系统)系统仿真可对双频GPS 接收机的设计、接收算法的研究 提供有效的帮助。文中详细介绍了在MatLab/Simulink 环境下GPS 系统仿真平台构建的基本方法。 首先分析了GPS 系统的各个环节，说明了各模型在仿真中的实现方法；然后给出了完整的系统仿 真框图，并在此平台上实现了GPS L2 载波相位跟踪的仿真。结果表明该仿真平台有效、可靠(Fast and reliable GPS (Global Positioning System) system simulation of dual-frequency GPS receiver design, receiver algorithm to provide effective help. Text in detail in the MatLab/Simulink environment GPS system simulation platform to build the basic method. First, we analyze the various segments of GPS systems shows that the model in the realization of simulation methods and then given a complete system simulation block diagram, and on this platform realize the GPS L2 carrier phase tracking of the simulation. The results show that the simulation platform for effective, reliable)
