对通信信号的带宽以及信噪比参数的计算

使用 MATLAB 构造函数 Filter_1，实现对一张灰度图像的边缘检测操作。要求 Filter_1 的输入包括三个变量：I、Operator、Option。其中 I 为待处理的灰度图像，Operator 包含两个选项：Kirsch 算子和 Sobel 算子，他们的定义如图 1 所示。Option 包含两个选项：取最大和取和，这一操作仅对 sobel 算子有效，代表着算子不同方向分量滤波后的结果是取最大值还是直接求和，即max( , ) f f   。而根据 Kirsch 算子的定义，在八个方向的分量分别滤波后应该是取最大值，即Filter_1 的输出为一幅经过边缘检测后的边缘强度图像（注意输出结果应该是一张灰度图像，不应该直接输出边界的二值图）。

MMSE detection of frequency offset

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. )
