Der Aufbau eines kleinen Frequenzzä hers ist dank der heutigen Atmel AVR Controller oder aber auch der Mikrochip PIC Controller (um nur zwei zu nennen) relativ schnell und einfach aufzubauen. Dazu werden meist die internen Timer/Counter des Controllers benutzt. Der Counter wird durch das anliegende Signal Am Takteingang hoch gezä hlt. Durch den Timer wird dann der Counter zu einen festgelegten Zeitpunkt stetig ausgelesen und zurückgesetzt. Nehmen wir mal an ein 20Hz TTL-Signal taktet den Counter so steht nun im Counterregister nach einer Sekunde der Wert 20. Dieser wird nur noch auf dem Display oder serielle Schnittstelle ausgegeben. Nach einer erfolgreichen Auktion bei einen einschlä gigen Internet Auktionshaus, erwarb ich einige 7Segment Anzeigen, hierfür musste ich mir etwas einfallen lassen. Heraus kAm somit ein besagter kleiner preiswerter 50MHz Frequenzzä hler, den ich nicht vorenthalten will.

his an ecapsulation of the ICS - Internet Component Suite. ICS can be found at : http://users.swing.be/francois.piette/indexuk.htm Please take the time to look at the code and learn something. If you re a Dephi Pro, you can probably give me some tips as I Am still new to Delphi progrAmming.

This project allows you to learn communication systems in greater depth. It contains the Simulink files (*.mdl) which are block design files of various communication systems such as Am, DSB-SC, FM, PLL, Data Acquisition, Digital Data Transmission, PCM and Delta Modulation. The idea here is to implement experiments of a traditional communication lab using Simulink. Most of the block diagrAms are self explanatory. More information on the systems and their implementation can be found in the word documents included in the lab directories

This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I Am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.

You may have heard the Latest Brief web service on CodeProject.com. It provides several methods for web client progrAms to retrieve information about CodeProject.com, such as the latest article updates, the latest comments, and the latest lounge posts, etc. Some very popular articles on the CodeProject site make use of this service. In this article, I Am going to present a java client progrAm that uses soap message to call the methods of this web service. My progrAm is not a general java soap client, which means you cannot use it to call other web services directly. However, you can easily modify it for other web services. The progrAm uses only basic Java, it does not depend on any other external class library.
