这个程序是EMD进行后对IMF的各个能量进行计算得出每个分量的能量分布，这个种方法也是一种常见方法,其中还包括这特征提取后的绘制可视程序。(This procedure is carried out after the IMF EMD various energies calculated energy distribution of each component, this method is also a common method.)

DCT-and-Image-Compression
DCT and Image Compression
In the JPEG image compression algorithm, the input image is divided into
8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each
block. The DCT coefficients are then quantized, coded, and transmitted. The
JPEG receiver (or JPEG file reader) decodes the quantized DCT coefficients,
computes the inverse two-dimensional DCT of each block, and then puts the
blocks back together into a single image. For typical images, many of the
DCT coefficients have values close to zero these coefficients can be discarded
without seriously affecting the quality of the reconstructed image.
The example code below computes the two-dimensional DCT of 8-by-8 blocks
in the input image, discards (sets to zero) all but 10 of the 64 DCT coefficients
in each block, and then reconstructs the image using the two-dimensional
inverse DCT of each block. The transform matrix computation method is used.

混合载波频率偏移估计方案用于基于通用滤波多载波的系统
本论文中，一个混合载波频率偏移估计方案用于基于通用滤波多载波的系统。 此方案所述CFO估计器基于最小平方（LS）准则首先导出以获得粗略频率偏移估计使用大频率搜索步骤。 接着，通过其精确估计残留频率偏移自相关操作补偿。 该算法具有较大估计的特点范围以及更高的估计精度。(In this letter, a robust hybrid carrier frequency offset
(CFO) estimation scheme based on training symbols is devised
for universal-filtered multi-carrier (UFMC) based systems. In this
scheme, the CFO estimator based on a least square (LS) criterion
is firstly derived to acquire a coarse frequency offset estimation
with the use of a large frequency searching step. And then,
the residual frequency offset is accurately estimated through the
auto-correlation operation of received signals which have been
compensated. This algorithm has the features of larger estimation
range as well as higher estimation precision.)
