labviewserial

说明：  此范例说明 了在LABVIEW平台下进行船舶运动可视化仿真平台(This example illustrates the ship motion visualization simulation platform in LABVIEW platform)

labview中的虚拟示波器 特别好用 建议大家使用(labview virtual oscilloscope particularly useful to suggest that you use)

说明：  在界面更改信号幅值，频率，噪声标准差，可以实时显示含噪信号的信噪比大小。(By changing the signal amplitude, frequency and noise standard deviation on the interface, the signal-to-noise ratio of noisy signal can be displayed in real time.)

基于labview的数据保存与数据库调用源程序,非常哟用哦！(Labview-based data stored with the database source called，it is very useful!)

说明：  用于读取txt文本文件，并显示在labview中(Used to read the numbers in the txt file and display them in LabVIEW)

Labview与数据库Access及SQL Server的连接 基于ActiveX(Labview database connectivity Access and SQL Server ActiveX-based)

说明：  通过labview对BP神经网络进行训练，得到BP模型。(The BP neural network is trained by labview to obtain the BP model.)

基于labview的简易密码器程序，密码输入错误提示，多次错误退出程序(A simple password box program based on labview , when enter the incorrect password, a error message would show to you,and the program will exit when entering the wrong password for three times.)

基于labview的chirp信号联合时频分析，2012版本以上(Joint time-frequency analysis of chirp signal based on labview)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )
