在VHF的160Mhz-160.250Mhz的范围内的250KHZ频段上，设计一个FDMA通信系统，信息序列调制方式采用GMSK调制(In the 250KHZ band of the 160Mhz-160.250Mhz of VHF, a FDMA communication system is designed. The modulation of information sequence uses GMSK modulation)

Explanation about histogram and adjustment

说明：  我提供了一个基于FXLMS的单通道前馈有源噪声控制系统的一个小例子. 为了减少噪声，我们使用控制器C（z）产生另一个“噪声”yw（k）。我们希望它破坏性地干扰X（k）。这意味着控制器必须是传播介质P（z）的模型。采用最小均方算法对控制器系数/权重进行调整。 然而，还有流体介质S（Z）留在致动器和传感器之间。我们称之为二次传播路径。所以，为了使解正确，我们需要用SH（z）来补偿调整过程，这是S（z）的估计(I provided him a little example of a single channel feed-forward active noise control system based on the FxLMS. To reduce noise, we generate another 'noise' yw(k) using the controller C(z). We hope that it destructively interferes x(k). It means that the controller has to be a model of the propagation medium P(z). Least mean square algorithm is applied to adjust the controller coefficient/weight. However, there is also fluid medium S(z) that stay between the actuator and sensor. We called it the secondary propagation path. So, to make the solusion right, we need to compensate the adjustment process using Sh(z), which is an estimate of S(z).)

VC++ 删除目录或文件夹的例子。删除指定的文件夹目录的源码，请在文本框中输入需要删除的目录名称、路径即可，路径不要错哦，本示例主要是演示如何删除文件，在易用性方面没过多完善。 　　//是文件时直接删除 　　if (!file.IsDots() && !file.IsDirectory()) 　　 DeleteFile(file.GetFilePath()); 　　else if (file.IsDots()) 　　 continue; 　　else if (file.IsDirectory()) 　　{ 　　 path = file.GetFilePath(); 　　 //是目录时,继续递归调用函数删除该目录下的文件 　　 DelFolder(path); 　　 //目录为空后删除目录 　　 RemoveDirectory(path); 　　}
