Bit Error Rate simulation and theorique with SNR.

Monte Garlo 仿真程序，关于误码率与信噪比的对应关系，希望对大家学习有所帮助(Monte Garlo simulation program, on the bit error rate and signal to noise ratio of the corresponding relations and hopes to help them to learn)

说明：  信号统计分析技术实现信号统计分析技术随机信号的自相关于协方差(Signal statistical analysis techniques for signal statistical analysis of random signals Zixiang covariance)

说明：  请不要用做非法用途，本程序是经过本人亲自验证过的绝对好使，本人还有其他的一些源码，如果有赶兴趣的可以给本人发邮件(Please do not use illegal purposes, the procedure was personally tested the absolute so, I have some other source, if there is time to be interested in my mail)

OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

SAR距离多普勒仿真程序,通过Ｍａｔｌａｂ编出来的(SAR Range Doppler algorithm)

Differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on.
