说明：  利用锁相环来实现MSK信号的定时同步，采用的是gardner算法(Using phase-locked loop to achieve timing synchronization of MSK signal, Gardner algorithm is adopted.)

This is book about bluetooth programming and other items. Is good for beginerss.

说明：  通过matlab实现车联网下的资源分配，包括用户、路边单元和基站，相关毕设可以使用(Matlab is used to realize the resource allocation under the vehicle network, including users, roadside units and base stations, which can be used in relevant settings.)

此程序是c语言的有关LDPC译码仿真程序,很有用,LDPC的译码仿真可能对朋友有帮助()

说明：  安卓手机调用蓝牙实现热敏打印机打印，多品牌打印机可用(Android mobile phone calls Bluetooth to print thermal printers, multi-brand printers are available)

轻松抓图袖珍版,可以帮你轻易抓取屏幕上任意你想要抓取的活动窗口,按F3键将选中图像复制到系统剪切板中,方便你随时,随地粘贴(Easy to grab the picture pocket version, can help you easily grab any screen you want to grab the active window, press F3 button will be selected image copy to the system cutting board, easy to you anytime, anywhere paste)

GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more and more prevalent due to the ease with which they can be implemented, but the dynamic IP address issues associated with GPRS networking continue to frustrate system integrators.

说明：  调用webrtc中的VAD算法，可以实现录音文件的语音端点检测，时延7.8ms(Calling VAD algorithm in webrtc, voice endpoint detection of recording file can be realized with a delay of 7.8ms)

说明：  1、基带码型仿真 （1）通过仿真观察占空比为50%、 75%以及100%的单、 双极性归零码波形以及其功率谱，分析不同占空比对 仿真结果的影响。 （2） 通过仿真产生一随机消息码序列，将其分别转换为 AMI码和HDB3码，观察它们的波形及其功率谱密度。 2、数字带通调制系统仿真 设计一个采用2ASK（ OOK） 调制的数字通信系统： 产生二进制随机数据，并仿真其对应的2ASK调制波形， 分析其频谱。所产生的调制波形加入不同信噪比的白噪声， 选取合适的接收方案，画出系统误码率曲线，并与理论误 码率进行对比。(1.Baseband pattern simulation 2. Simulation of digital band-pass modulation system)
