labview数字调制解调

关于labview的USRP编写的扫频信号，观察其时域和频域波形(On the sweep signal written by USRP of labview, the waveforms in time domain and frequency domain are observed.)

使用LabVIEW对输入波形经行傅里叶变换，对比时域信号与频域信号。(LabVIEW for use by the line of the Fourier transform of the input waveform, compared to the time domain signal and frequency domain signals.)

说明：  噪声检测，声卡采集，频率分析，数据统计分析，均方根(Noise detector,Sound card acquisition,frequency analysis,Statistical analysis of data,Root mean square)

说明：  LabVIEW编程样式 中文版 清晰度一般(the labview style book (chinese))

小波去噪算法及传统去噪算法在LabVIEW中的比较(Comparison of wavelet denoising algorithm and traditional denoising algorithm in LabVIEW )

本文通过运用myDAQ搭建一个在线音效处理系统，利用LabVIEW控制myDAQ完成信号的采集、分析以及发生。 (By using myDAQ build an online audio processing system, using the LabVIEW Control myDAQ complete signal acquisition, analysis, and happen.)

说明：  【智能四路交通灯控制系统模拟】 这款交通灯模拟系统基于labview软件开发，界面全部自己设计，简洁明了，功能多样化、实用化、具体化，最大程度还原真实的十字路口交通灯控制系统。在以往单纯的红绿交替变化上添加功能如下 1.数码管倒计时功能和灯光闪烁功能，四路人行道灯。 2.配备有操作板可以人为设置各路口交通灯的亮灭时间、闪烁频率，报警器频率，字符串提示。控制暂停和全灭。 3.数码管显示的系统实时年月日及时间。 4.显示以及交通管制中的7种模式（普通模式、三向禁行、南北通行、东西通行、夜间模式、维修模式、紧急模式）和每种模式持续的时间（用计时器来体现）。 现实中可以根据实际路况和需要进行有目地的调整，使交通更加通畅高效。([simulation of intelligent four-way traffic light control system] 1. Digital tube countdown function and light flashing function, four-way sidewalk light. 2. Equipped with operation panel, it can manually set the on / off time, flashing frequency, alarm frequency and string prompt of traffic lights at each intersection. Control suspension and total extinction. 3. The real-time date and time of the digital tube display system. 4. Display and seven modes in traffic control (general mode, three-way traffic prohibition, north-south traffic, east-west traffic, night mode, maintenance mode, emergency mode) and duration of each mode (reflected by timer). In reality, it can be adjusted according to the actual road conditions and needs to make the traffic more smooth and efficient.)

输控制协议（TCP，Transmission Control Protocol）是一种面向连接的、可靠的、基于字节流的传输层通信协议，由IETF的RFC 793定义。TCP旨在适应支持多网络应用的分层协议层次结构。(Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol defined by IETF RFC 793. TCP aims at adapting to the hierarchical protocol structure supporting multi-network applications.)

labvIEW程序，可以把一个数组转化为一个簇的形式(labvIEW program, you can put an array into a cluster)

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)
