speed and position control of dc motor

介绍了关于memory的相关函数，对于大多数程序员有很大帮助，希望大家多多使用(the information about memory)

In this letter, we employ orthogonal random beam-forming (ORBF) for the worst-case multi-user downlink scenario whereeachuseriswiretappedby one eavesdropper. Two oppor-tunistic scheduling techniques that ensure confidentiality by ex-ploiting multi-user diversity are investigated thefirst technique (optimal) requires limited feedback of the effective signal-to-in-terference ratio (SIR) from all the users

说明：  自适应控制使用李雅普诺夫推导自适应律的学习程序(Adaptive control uses Lyapunov to derive adaptive law)

用于去除背景，得到原图与背景相减的图像并二值化(To remove the background, the subtraction image and background image and binarization)

这个程序可以演示关于哲学家就餐的问题，对于理解线程的相互等待有很好的作用(This procedure can be demonstrated on the Dining Philosophers problem, each thread to wait for understanding the role of good)

信道估计仿真，采用了多种方法：线性插值，MMSE，1惟MMSE,2维MMSE等(Channel Estimation 1 for non-block-wise linear interpolation, 2 for block-wise 1-D MMSE, 3 for non-block-wise 1-D MMSE, 4 for block-wise 2-D MMSE, 5 for non-block-wise 2-D MMSE, 6 for ideal channel estimator, 7 for random pilots map case using 2-D MMSE.)
