gmsk modulation of numerical data generated by a random source, the output of the modulator give two signals, the first is gmsk signal and the other is gaussien frequency pulse shape

Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected thr ...

A certification path is an ordered list of certificates starting with a certificate issued by the relying party s trust root, and ending with the target certificate that needs to be validated. Certification path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509 ...

（1）通过开关K0合上与断开控制A/D转换的开始和停止，当开始A/D转换后，每秒对连接到PTB3的模拟量采样一次，结果送指示灯D7~D0显示。 （2）采样结果同步通过串行接口发送到PC机（38400bps，N，8，1），显示格式为“The signal is:x.xV”（满量程为5.0V）。 ...

With the Wireless module, OPNET can model both terrestrial and satellite radio systems. In this tutorial, you will use Modeler and Wireless modeling to create a radio network you will also observe variations in the quality of received signal that results from radio noise at the receiving node in a ...

This paper presents a new adaptive mobility-aware MAC protocol for sensor networks (MS-MAC). The protocol uses any change in received signal level as an indication of mobility and, when necessary, triggers the mobility handling mechanism. By doing this way, the new mobility-aware MAC protocol can wo ...
