这个是对一般信号进行快速傅里叶分析。并画出其幅频图和相频图。与原信号进行比较(This is the general signal fast Fourier analysis. And draw the amplitude frequency and phase frequency diagram. Comparing with the original signal)

calculate the Hurst exponent

The aim of the assignment is to understand the concept of the image enhancement stage We need to know the technique to improve the image or better input for the image processing technique as in the assignment. In the first part of the assignment is the segmentation using thresholding technique. Before we threshold the image, we need to prepare the better image for input such as histogram equalization to stretch the intensity value of the image before converting to binary image. In the second part of the assignment is about frequency domain. We need to transform the spatial image to frequency image using Fourier transform of the image before using the filter.

采用信号包络和差分方式进行信号模式识别，通过变换产生时域解析信号SKH ，即信号的复包络，得到零中心归一化瞬时绝对值的标准偏差。 (Differential use of signal envelope and the way the signal pattern recognition, transformation generated by time domain analytic signal SKH, the signal complex envelope, zero-center normalized standard deviation of the instantaneous absolute value.)

polar码的SC译码算法，可设置不同信噪比，不同码长，可改为SCL算法和CA_SCL算法。核心部分采用C程序编写，主要框架采用matlab编写，极大提高了运行速度。 (SC polar code decoding algorithm, you can set different SNR, different code lengths, can be changed SCL algorithm and CA_SCL algorithms. The core part of C programming, the main framework for the use of matlab prepared, greatly increasing the speed.)
