说明：  matlab 卫星N 文件、O文件读取，计算出卫星坐标和测站坐标，精度为10M左右(matlab satellite N files, O file read, calculate the satellite coordinates and station coordinates, and an accuracy of about 10M)

仿真OOK载波调制信号在AWGN信道下的误码率和误比特率性能，并与理论值相比较。 OOK是ASK调制的一个特例，把一个幅度取为0，另一个幅度为非0，就是OOK。(OOK modulation signal simulation in AWGN channel bit error rate and bit error rate performance, and compared with the theoretical value. OOK is a special case of ASK modulation to an amplitude taken as 0, and the other non-zero amplitude is OOK.)

自己编程产生一种四进制相位调制信号，为数字调制信号的识别做准备。(programming to produce a quaternary phase modulation signal, the recognition of digital modulation signals in preparation.)

DFIG system, including a wind turbine, a generator, power electronic converters and power system grid are modeled. All of the control algorithms and operation modes are simulated. The active power is always controlled at maximum output while the reactive power is controlled to achieve a particular power factor or line voltage. Second, a complete DFIG wind power test bench including a wind turbine emulator is designed and built. The back-to-back converters are designed to control the DFIG. A Microchip d

说明：  结构动力学算例，运用mirison和matlab语言，写了一个波浪力的算例(A numerical example of structural dynamics is given. a numerical example of wave force is written by using mirison and MATLAB language.)

求梅尔倒谱系数的matlab程序，主程序是melcepst。(Mel Cepstrum Coefficients seeking matlab program, the main program is melcepst.)

说明：  该算法为连续系统的模拟PID仿真,用MATlab开发，能够管直接运行,其中以二阶传递函数为控制对象进行PID仿真(The algorithm for continuous system simulation PID simulation, using Matlab development, be able to pipe directly to run, with second-order transfer function for PID control simulation objects)

pwm整流器的MATLAB仿真程序，都正确。(MATLAB PWM conventer)

OFDM系统中信道估计基于LS改进算法--基于DFT的信道估计算法实现(LS channel estimation in OFDM system based on the improved algorithm based on DFT channel estimation algorithm )

可用传输容计算程序，采用直流潮流计算，速度快。(Available transmission capacity calculation procedures, the use of DC power flow calculation speed.)
