USTM
快衰落多输入多输出信道中,无信道状态信息的酉空时调制。属于信道发射和接收两端均无信道状态信息的非相干空时码。程序包含一个主程序和一个酉空时信号产生子程序,并给出误比特率。(Unitary space-time modulation without channel state information in fast fading MIMO channels. It belongs to the incoherent space-time code with no channel state information at both ends of the channel transmitting and receiving. The programs include a main program and a unitary space-time signal generation subroutine, and gives the bit error rate.)

LFM_BC
一种基于LFM和Barker码复合调制的雷达波形,理论上分析了该低截获雷达波形的组成。通过仿真得到复合调制信号的时域波形、频谱图和模糊函数图,与LFM信号和Barker码信号对比分析对复合调制雷达信号的距离和多普勒模糊函数、截获因子等进行了研究。(A radar waveform based on LFM and Barker code modulation is presented. The composition of the waveform is analyzed theoretically. The time domain waveform, spectrum and ambiguity function of the compound modulation signal are obtained by simulation. The range and Doppler ambiguity function and interception factor of the compound modulation radar signal are studied by comparing with LFM signal and Barker code signal.)

COM_customplot
说明: 自己用的小软件,仿造原子的XCOM功能,加了一下自己用的功能。
1、基本串口通讯,鼠标放入串口选择自动刷新,显示COM口的驱动类型。
2、多条发送界面,可定时发送,可关联数字键盘、右键发送按钮可更改按钮名称,方便记忆。
3、485通讯,数据有十进制和十六进制可选,发送后自动保留记录。
4、CRC校验小工具。
5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制
6、字符格式示波器,例:">P:-1.25",示波器显示曲线名称P,数值-1.25,曲线个数最多8个。
7、类似MODBUS协议截取第2-5位,合成一个int数值,然后示波器显示波形,最多5个曲线
8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)
