ofdm的simulink仿真程序，经过本人验证，绝对好用!(The OFDM simulink simulation program, after I verified, the absolute ease of use!)

matlab心形~压缩包内有两个function函数，代入数据，很容易使用(matlab is very easy to use heart-shaped ~)

Matlab源代码读取PCM文件，路径需要修改下 (Matlab source code to read the pcm file, the path need to modify under )

This project proves to be a very useful home and office appliance as it eliminates the worry of user to open & close a door. In this project we have not operate door as we did manually as push and pull a door.Project circuit sens a human interference and accordingly it is open & close door. The term automated doors includes full powered automated doors such as those that are commonly used at supermarkets and transportation terminals and low energy and “power assist doors that are used in less demanding situations. Here it doesn’t require conventionally pull and push the door. So it can be useful for Handicap people. It is easy to use and affordable.

ESPRIT是“Estimating signal parameters viarotational invariance techniques”的缩写，含义是“借助旋转不变技术估计信号参数”，它是由Roy[221等人于1986年提出的另一种基于子空间的DOA估计方法。 应用领域 　　侧向定位 信号处理 思想 　　ESPRIT的思想在于，将传感器阵列分解为两个完全相同的子阵列，两个子阵中每两个相对应的阵元具有相同的平移，即要求阵列具有平移不变性，每两个位移相同的阵元匹配成对。所幸的是实际中许多阵列满足这个条件，比如等距直线阵。(ESPRIT is "Estimating signal parameters viarotational invariance techniques" acronym, meaning "With ESPRIT estimation of signal parameters", it is by Roy [221, who in 1986 proposed DOA estimation method based on subspace another. Applications Lateral positioning signal processing Thinking ESPRIT thinking that the sensor array is divided into two identical sub-arrays, each of the two sub-arrays of two corresponding array element has the same translation, which requires an array with translation invariance, the displacement of each of the two identical arrays yuan matching pairs. Fortunately, many of the actual array satisfy this condition, such as equidistant linear array.)
