主要就是实现L_M优化算法，用matlab写的 转成c该很容易的，用来仿真用的，希望大家给出点意见，第一次上传(err)

很好的课件！里面涉及了；老师上课的所有内容，对于学习模式识别的同学，有较好的参考价值！(Good courseware! Which involves the teacher in class all the content, pattern recognition for the students to learn, have good reference!)

自己用Simulink做的mc_cdma链路仿真，运行结果还不错，有需要的可以参考一下(Their own to do with the mc_cdma link Simulink simulation, the results also is true that there is a need to look at the can)

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.

西储大学轴承数据，故障特征频率明显，与理论值基本符合。(The bearing data of Xichuan University have obvious fault characteristic frequency, which is basically in accordance with the theoretical value.)

关于matlab计算的代码，主要为拉曼激光器输出与输入的关系，希望大家下载啊(Calculated on the matlab code, mainly for the relationship between the Raman laser output and input, I hope you download ah！)
