NLMS Adaptive filter for voice

用matlab编写中点画圆算法的程序，原理是：先从(0,R)点画第二个八分之一圆，再利用圆的八对称性，可画出其余七个八分之一圆。( Compiles the center point makeing a circle algorithm with matlab the procedure )

说明：  经典ESPRIT算法，在等间距接受阵列的条件下，直接估计出我们想要接收信号的角度。八个接收天线，二个目标信号，噪声为高斯噪声。(Classical ESPRIT algorithm, such as spacing in the array to accept the conditions, we want to directly estimate the received signal point of view. Eight receiving antennas, two target signal and noise as Gaussian noise.)

Nginx Markdown module 一个nginx模块，可以将网页中的markdown语法自动转义为html,无需引入其他支持库，执行效率高。 使用--add-module编译Tengine可用dso_install动态加载。 设置实例(http块) location ~ /*.md { mdfilter on mdfilter_utf8 on } // Use Handler module location ~ /*.mkd { mdhandler mdhandler_output html }(Nginx Markdown module a nginx module can be a Web page markdown syntax is automatically escaped as html, without introducing additional support libraries, and high efficiency. Use- add-module compiled Tengine available dso_install dynamic loading. Set the instance (http block) location ~ /* md {mdfilter on mdfilter_utf8 on }.// Use Handler module location ~ /* mkd {mdhandler mdhandler_output html }.)

描述了利用矩阵方式产生单极性归零码的过程，并给出单极性归零码的码型和功率谱。(Matrix describes the way the use of unipolar NRZ process, and gives the code NRZ unipolar and power spectrum.)

关于matlab的基础语言和其他算法，有利于初学者(Based on the matlab language and other algorithms, help beginners)

pure aloha 和slotted aloha算法的 matlab代码。结果显示了两种算法吞吐量的对比，通过修改标签数也可以得出吞吐量的变化值。 纯ALOHA协议(Pure ALOHA) 当传输点有数据需要传送的时候，它会向立即向通讯频道传送。 接收点在收到数据后，会ACK传输点。 如果接收的数据有错误，接收点会向传输点发送NACK。 当网络上的两个传输点同时向频道传输数据的时候，会发生冲突，这种情况下，两个点都停止一段时间后，再次尝试传送。 因为有太多的传输冲突.(pure aloha and slotted aloha algorithm matlab code. The results show the comparison of the two algorithms throughput, by modifying the number of labels can also come to change the value of the throughput. Pure ALOHA protocol (Pure ALOHA) When the transfer point has data to transmit, when it would have to immediately transfer to the communications channel. After receiving the data reception point will ACK transmission points. If the received data has an error, the receiver sends NACK point to point transmission. After transmission when two points on the network at the same time to the channel to transmit data, it will conflict, in this case, two points are stopped for some time, try the transfer again. Because there are too many transmission conflict.)
