beamforming codebook design for MIMO system

说明：  神经网络滑膜变结构控制MATLAB和simulink仿真程序。(Variable structure neural network control of synovial MATLAB and simulink simulation program.)

一个简单卡尔曼滤波的例程，国外网站下载的，m文件详细说明了卡尔曼滤波器的设计过程(A simple Kalman filtering routines, Abroad website)

电机模型，使用matlab语言。 在simulink环境下使用(Motor model, using the matlab language. Used in the simulink environment)

事先计算图像的标准差，可以用来评判图像变换是否可信(Calculate the standard deviation of the prior image can be used to judge the credibility of image transformation)

以正弦波信号为例，对其进行信源编码、译码，循环信道编码(a sinusoidal signal as an example, its source coding, decoding, channel coding cycle)

把三角函数的和 按周期的不同 把需要的周期函数 抽出来 相当于滤波器的作用(The trigonometric functions and the need to press the different cycles of periodic functions to extract the equivalent filter function)

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.

ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)
