MUSIC，多重信号分类法，基于子空间分解，是DOA估计中的经典高分辨方法，初学者必须懂的。(MUSIC, multiple signal classification method based on subspace decomposition, is the classic high-resolution DOA estimation method for beginners to understand.)

这是频域副本相关的代码，给予信号同样长度的副本，使得信号在相关后可以恢复，先是通过滤波器，然后找出信号点。(This is related to the frequency domain replica code, a copy of the same length given signal so that the signal can be restored after correlation, first through a filter, and then identify the signal points.)

蒙特卡洛模拟法是当系统中各个单元的可靠性特征量已知，但系统的可靠性过于复杂，难以建立可靠性预计的精确数学模型或模型太复杂而不便应用则可用随机模拟法近似计算出系统可靠性的预计值。随着模拟次数的增多，其预计精度也逐渐增高。由于需要大量反复的计算，一般均用计算机来完成。本文件用来求解医院排队论问题(Monte Carlo simulation when the system reliability characteristics of each unit volume is known, but the reliability of the system is too complicated, difficult to establish accurate mathematical model of reliability prediction models are too complex or inconvenient applications are available stochastic simulation method to approximate calculation the expected value of system reliability. With the increase in simulation times, which is expected to gradually increase precision. As the need for a large number of repeated calculations, generally using the computer to complete. This document is used to solve the problem of queuing theory Hospital)

order static是在天线选择，用户选择中经常使用到的方法，这本书详细介绍了关于orderstatic的理论(order static in antenna selection, the user selects the method often used, this book details the theory on the orderstatic)

一个用MATLAB写的关于锐利信道仿真的例子，希望对通信开发的同志们有用(a MATLAB write on the sharp channel simulation examples, and I hope to the development of the communications useful comrades)
