上位机软件动态获取计算机COM口
应用背景
通过MFC6.0生成一个单文档程序,然后新建一个对话框并生成一个新类;在对话框中添加两个组合框控件。在生成的新类上右击增加windows消息WM_INITDIALOG生成处理函数,函数内容见“关键技术描述”。函数体中的index和baud均为int型,可设为全局变量。
关键技术BOOL CComDlg::OnInitDialog()
{
CDialog::OnInitDialog();
((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("4800");
((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("9600");
((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("38400");
((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("115200");
((CComboBox *)GetDlgItem(IDC_COMBO2))->SetCurSel(0+baud);
long lReg;
HKEY hKey;
DWORD MaxValueLength;

6*6mimo ofdm with USRP
应用背景This document describes how to set up a 6x6 multiple input, multiple output (MIMO) system using NI LabVIEW software and NI USRP™ (Universal Software Radio Peripheral) hardware. After a brief discussion of MIMO, the paper examines the hardware and software based on LabVIEW for a 6x6 MIMO-OFDM system using 4-QAM as modulation scheme. The system presented here is also capable of working as a 2x2 MIMO and 4x4 MIMO system with appropriate parameter configuration.关键技术With MIMO, you can increase wireless system performance without increasing power consumption. It is based on the idea that when using multiple antennas, the transmitted signal progresses through different wireless channels, from the transmitter antennas to the receive antennas, to
