是关于生成QAM 仿真的程序码,可以帮助你用编程的方法完成QAM调制解调系统的仿真(it is something about 16-QAM,it can help you simulink QAM with MATLAB )

说明：  VB6.0开发道闸控制程序，程序控制开闸、落闸(failed to translate)

控制蓝牙Dongle 通过蓝牙地址自动配对 (Cotrol the IVT dongle let it paied the bluetooth that you want to test.)

说明：  产生数字基带信号，加入AWGN高斯白噪声在信道中传输，检测出原始基带信号，并绘制理论和仿真误码率曲线(The digital baseband signal is generated and transmitted in the channel with AWGN white Gaussian noise. The original baseband signal is detected and the theoretical and simulation BER curves are drawn)

GPRS fundamental review

MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task.)

这是一个用CVI编写的模拟标准频谱仪界面，包含了前面板和各种常用的输入按键。(This program is developed by CVI used to simulate a standard interface of spectrum analyzer ,presented with popular keys and functions.)

说明：  这是一个基于OPtisystem下的对于8PSK信号的仿真，可用于通信工程作业的一般仿真系统。(This is a simulation system of 8PSK signal based on OPtisystem, which can be used in general simulation system of communication engineering operation)

HLP A+ Modbus 标准通讯协议格式，上位机发送数据格式，正确时变频器返回数据格式(This bit will be set to logic 1 when the receive buffer has been read and contains no new information. If there is new information available in the receive buffer that has not been read, this bit will return to logic 0. RXBMT = 1 when in Master Mode.)

子载波功率资源分配，OFDM技术将信道分成许多正交子信道，在每个子信道上使用一个子载波进行调制，并且各个子载波并行传输(Power resource allocation of the sub-carriers, OFDM technology will channel into a number of orthogonal subchannels, in each subchannel to use a sub-carrier modulation, and the respective sub-carrier parallel transmission.)
