1. INTRODUCTION Recently, there has been increased interest in the simulation of large-scale radio networks. Two major and conflicting obstacles in the simulation of large-scale radio networks are the simulation run time and the accuracy of the simulation results. Since all projects have time constrains, it is often not impossible to conduct lengthy simulation experiments. In our experience, fo...

VLSI in Mobile Communications

In recent years, the demand for mobile operation of all types of electronic systems has become significant. It seems that by merely providing the same functionality of a desktop system in a mobile unit, a significant market advantage can be obtained for virtually any electronic function. Consumer electronics companies have been highly successful by creating portable televisions, video tape reco...

Wireless and Mobile Communications

Figure 1 gives a rough overview of some prominent wireless communication systems focusing on the two parameters gross data rate and relative speed between sender and receiver. Assuming a mobile end-user connected to a stationary transceiver station, the points on the (non proportional) speed axis resemble nonmoving persons, pedestrians, cars downtown, cars outside cities, and cars on a highway,...

Generation of Mobile Communications

Despite the fact that 4G deployment is still at its infancy there are already many research initiatives that focus on the next generation of mobile communications. But why there is a need for a new generation to be shaped so closely to the previous one? Is it really a need behind it by the community or the companies are seeking new ways to sustain or enhance their profits. In this paper we high...
