d2gauss

说明：  使用matlab进行摄像机标定，具有较高的精度，操作简单，提供应用使用说明(Using matlab to camera calibration, high accuracy, simple operation, to provide application instructions)

用两点法辨识一阶惯性滞后系统，测试结果比例系数和时间常数辨识结果较准确，但输入延迟时间差距较大，分析其原因，可能是因为在曲线上取的两点坐标不准确，因为离散的数字量坐标取值方法有误。(Two points )

球体磁异常源码适用于地球物理方面的重力异常反演解释及其推演(Magnetic anomaly source code for the application of gravity anomaly inversion interpretation and deduction in the field of Geophysics)

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)
