the code simulates the MIMO-OFDM spatial multiplexing with successive interference cancellation

仿真实现了谱相关系数和谱相关函数，谱相关函数使用了频域计算法。谱相关函数做的比较好，但谱相关系数的计算个人感觉仍需后来者继续改进(Simulation spectral correlation coefficient and spectral correlation function, the calculation of the frequency domain using the spectral correlation function. Spectral correlation function do better, but the spectral correlation coefficient calculated personal feeling is still a latecomer to continue to improve)

将小波相邻系数相关性的降噪思想引入到冗余第2代小波中，提出了基于邻域相关性的冗余第2代小波降噪方法，该方法克服了传统阈值降噪没有考虑小波系数之间相关性的不足。(Aiming at fault feature extraction in the background of strong noise, a wavelet denoising idea by incorporating neighboring coefficients is introduced into redundant second generation wavelet case. A denoising method of redundant second generation wavelet using neighbor dependency is presented. It overcomes the deficiency of traditional thresholding approaches. In this method, an original signal is decomposed by redundant second generation wavelet, and the detail and approximation signals have the same length as the original signal. The detail signals at each scale are then processed by neighbor dependency. Finally, the approximation signal and processed detail signals are reconstructed by inverse transform of redundant second generation wavelet to realize the signal denoising. )
