信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )

基于均匀圆形麦克风阵列模型的延时-求和波束赋形成(Delay-Sum Beamforming based on the uniform circular microphone array model)

In this code we used a fingerprint as cover and a text image as hidden image by using wdt to enhance security for sending our text.

对激光通过大气传输的主要非线性过程进行数值模拟, 列出大气的流体动力学方程组和与 大气相互作用的波方程，推导出受激热瑞利散射引起的小扰动不稳定性的波与大气的耦合方程, 还对湍流作了处理。(Of laser transmission through the atmosphere, the main non-linear process to simulate the fluid dynamics are listed in the atmosphere and atmospheric interaction equations and the wave equation is derived by stimulated thermal Rayleigh scattering instability caused by the wave perturbation coupled equations with the atmosphere, but also made a deal with turbulence.)

利用FDTD算法，计算fopen环境下的雷达散射截面积。(Use FDTD algorithm to calculate fopen environment RCS.)
