matlab 16 qam 调制的代码。将调制信号先分成IQ两路，再进行信号的调试。(Matlab 16 QAM modulation code. The modulation signal is first divided into two IQ paths, and then the signal is debugged.)

利用RSS进行室内定位仿真实验在RSS指纹数据库中抽取离线数据集；利用抽取出来的数据集作为KNN算法的训练数据集；(RSS is used for indoor positioning simulation experiments to extract offline data sets from RSS fingerprint database, and the extracted data sets are used as training data sets of KNN algorithm.)

说明：  1. 硬件接线 （1）调试串口(UART_Debug)使用UART2，在“printf.h”文件中宏定义， 对应引脚为TX-PTD7，RX-PTD6 （在“uart.h文件中宏定义）。 （2）灯0~3（LIGHT_0~LIGHT_3）对应的引脚是PTC0~PTC3，高电平点亮（由硬件接法决定） （3）SPI0_CLK对应的引脚是PTE0， SPI0_MOSI对应的引脚是PTE1， SPI0_MISO对应的引脚是PTE2，SPI0_PCS对应的引脚是PTE3， SPI1_CLK对应的引脚是PTG4， SPI1_MOSI对应的引脚是PTG5， SPI1_MISO对应的引脚是PTG6，SPI1_PCS对应的引脚是PTG7。 （4）SPI0作为master,SPI1作为slave，SPI1接收SPI0发送的数据并产生中断。 用导线将PTE0与PTG4对接，将PTE1与PTG5对接，将PTE2与PTG6对接，将PTE3与PTG7对接。(1. Hardware wiring (1) Debugging Serial Port (UART_Debug) uses UART2, macro-defined in "printf.h" file, corresponding pins are TX-PTD7, RX-PTD6. (macro definition in the uart.h file). (2) The pins corresponding to the lamp 0~3 (LIGHT_0~LIGHT_3) are PTC0~PTC3, and the high-level lighting is determined by the hardware connection. (3) The pin corresponding to SPI0_CLK is PTE0, and the pin corresponding to SPI0_MOSI is PTE1. The pin corresponding to SPI0_MISO is PTE2, and the pin corresponding to SPI0_PCS is PTE3. The pin corresponding to SPI1_CLK is PTG4, and the pin corresponding to SPI1_MOSI is PTG5. The pin corresponding to SPI1_MISO is PTG6, and the pin corresponding to SPI1_PCS is PTG7. (4) SPI0 acts as master and SPI1 acts as slave. SPI1 receives data sent by SPI0 and generates interruption. PTE0 and PTG4 are docked by wire, PTE1 and PTG5 are docked, PTE2 and PTG6 are docked, PTE3 and PTG7 are docked.)

Visual C#显示隐藏鼠标的一个例子，隐藏鼠标后，使用Tab键移动光标，从代码中可发现，隐藏鼠标只需将ShowCursor(false);即可，显示时就这样：ShowCursor(true);面向C#初学者。下面是核心的代码： 　　//重写API函数 　　[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "ShowCursor")] 　　public extern static bool ShowCursor(bool bShow); 　　private void btnHide_Click(object sender, EventArgs e) 　　{ 　　 ShowCursor(false);//鼠标隐藏 　　} 　　private void btnShow_Click(object sender, EventArgs e) 　　{ 　　 ShowCursor(true);//鼠标显示 　　}
