将信号映射到小波域，根据噪声和噪声的小波系数在不同尺度上具有不同的性质和机理，对含噪信号的小波系数进行处理。实质是减少剔除噪声产生的小波系数，最大限度的保留真实信号的系数。 (Will be mapped to the signal wavelet domain, according to noise and noise of wavelet coefficients in different scales with different properties and mechanism of signal with noise of wavelet coefficients for processing.Essence is to reduce the noise out of wavelet coefficients, the maximum keep the coefficient of true signals. )

Basic rocket landing simulation in Matlab.

This text provide good training for general use of Matlab and numerical programing application of Matlab

Performance analysis of steganography is done for selecting better wavelet for application by analyzing Peak Signal Noise Ratio(PSNR) of different wavelet families like Haar, Daubechies, Biorthogonal, Reverse Biorthogonal & Meyer wavelet(dmey) on result oriented basis using Matlab environment.
