Description: 经典的数据挖掘分类算法，由ID3算法演变而来。本算法主要用于处理连续属性值，基本过程如下：
1.根据属性的值对数据集排序
2.用不同的阈值将数据集动态的分类
3.迭代根据阈值进行划分
4.得到所有可能的阈值、增益以及增益比-classical classification of data mining algorithms, evolved from the ID3 algorithm. This is mainly used to deal with continuous attribute values, the basic process is as follows : 1. According to the values of attributes of sorting two data sets. different thresholds of data sets dynamic classification 3. According iteration threshold Progressive - draw 4. all possible threshold, and gains than Gain

Description: 针对锁频锁相器( Phase and Frequency Detector, PFD) 应用于低信噪比、大频偏的条件, 通过理论分析和仿真验证阐述了窗口类型对系统频偏捕获速度、范围、噪声门限及相位噪声抖动的影响机理. 推导出等效相位噪声功率谱密度的表达式. 证明了大窗口具有更低的噪声门限和更小的稳态相位抖动, 但捕获速度较慢. 为了提高捕获速度, 对鉴相器输出值取极性运算得到改进的PFD 算法. 新算法不仅能增加鉴相增益提高捕获速度 还可以减少等效噪声功率谱密度降低相位抖动 同时新算法不需要乘法器便于硬件实现. 最后新算法的性能通过仿真得到了验证.-For frequency-locking phase-locked (Phase and the Frequency Detector PFD) conditions applied to the low signal to noise ratio, frequency offset, through theoretical analysis and simulation described the capture speed of the window type, the system frequency deviation, range, noise threshold and phase noise jitter mechanism. equivalent phase noise power spectral density expression is derived to prove the large windows with a lower noise threshold and the steady-state phase jitter, but to capture slow in order to improve the capture speed, The phase detector output value to take the polarity operator improved PFD algorithm. new algorithm not only can increase the phase gain to improve the capture speed can also reduce the equivalent noise power spectral density to reduce the phase jitter new algorithm does not require a multiplier to facilitate hardware implementation performance of the last new algorithm has been verified through simulation.

Description: 误差扩散是一种比较流行且效果较好的半色调方法，最早是由 Floyd-Steinberg 在 1975 年提出的，长时间以来，此方法一直被广泛应用。其基本思想是先按照确定的阈值量化图
像的像素，然后将量化误差以特定方式扩散到未处理的相邻像素上。这种方法需要进行
邻域处理，它能够为打印设备提供更高的半色调质量并且不引起网点增大，产生的半色
调图像无明显龟纹，视觉效果较好。-Error diffusion is a more popular and better halftone method was first proposed by the Floyd-Steinberg in 1975, a long time, this method has been widely used. The basic idea is to first determine a threshold pixel value according to the quantized image, and the quantization error diffusion in a particular way to the neighboring unprocessed pixels. This method requires neighborhood processing, it can provide a higher quality halftone printing equipment and does not cause dot gain, halftone image produced no obvious moire, visual effects better.
