QPSK_BER_Es

说明：  多用户检测 好多好多程序 MMSE 等等(Multi-user MMSE detection of all sorts of procedures)

设计一个合成信号，合成信号包含30H、50Hz、80Hz，可以用正弦或余弦或雷克子波，要求消除50Hz信号(Design a synthetic signal, synthesized signal contains 30H, 50Hz, 80Hz, can be used or Ricker sine or cosine waves, requires the elimination of 50Hz signal)

matlab采用半色调技术对图像进行显示：用模板近似表示10个灰度级，每一个灰度级用3*3 的模板来表示，并对如下图所示的256*256的渐变图像进行半色调输出的检验。(matlab using halftoning image display: template approximated 10 gray levels, a gray level of each template used to represent the 3* 3, and the gradation of the image as shown in Figure 256* 256 halftone inspection of the output.)

说明：  用MatLab将众多图片文件自动生成avi电影文件(Make a avi file from many picture file using Matlab program)

Pcnn神经网络筛选特征因子代码，pca预处理代码，特征因子整合代码，等等，都是好东西啊(Pcnn neural network filter characteristic factor code, pca pretreatment code, characteristic factor integration code, etc., are all good things ah)

matlab code for Toolbox Wavelets

利用meanshift1算法实现视屏目标的跟踪，包含全套程序，并配有示例视屏。(Meanshift1 algorithm to track the use of screen targets, including a full program, and with a sample screen.)

主要是用于产生cdma通信信道当中相关内容(Is mainly used to produce cdma communication channel among the relevant content)

laboratory 6 you can know the method predicting speech

CSMA/CD(1-persistent): 当有packet需要发送时： • 如检测到信道空闲，发送packet • 如检测到信道忙，一直检测信道状态，一旦信道空闲，立即发送(CSMA/CD (1-persistent): When there is packet needs to be sent when: • If the channel is detected idle, transmit packet • If the channel is detected busy channel state has been detected, once the channel is idle, transmit immediately)
