As mentioned, most computers include a serial port. The only hardware setup required is connecting the serial cable to the serial port on the PC and the serial port on the instrument. The serial instrument may include some hardware drivers or software utilities for communication, and should include documentation on the baud rate, packet size, stop bits, and parity bits that the instrument will use. Additionally, check the National Instruments Instrument Driver Network to see if LabVIEW drivers already exist for yout instrument, as

this application program demonstrate programming and simulation of the on-chip CAN (controller area network) interface of the C167/ST10-F168. The sample source code can be compiled using keil C166 compiler. To test the program you may use the uVision2 debugger/simulator that is part of keilPK166 package.

This paper presents the results of the Finnish national "Technology Vision of the Future Distribution Network" project. The aim of the project was to create a technology vision of future distribution networks. Because the life span of networks is very long, a long term vision is very important for guiding network investments and technology development.

Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi

After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mobile radio networks, the needs of large user groups, and relevant regulatory and government decisions. A final section focuses on career development through resolution of conflicts, understanding managerial issues, and professional vehicles.

Peers is a very minimalistic SIP User-Agent. It s a softphone, written in java, and it has been tested on linux and windows. It allows a user to call from one PC to another on a local area network, using SIP/SDP/RTP with Ulaw encoding for voice.

Application (fix point) for playing MP3 data on embedded systems. mp3play is designed to be able to play mp3 data files within the local filesystem (which can be a network filesystem), or fetch files to play via http over a network. For the http case the address can specify a streaming MP3 server.
