Abstract

This article proposes, modulation study with multi-levels QoS analysis, which can be used to perform physical layer functions for new generation systems. The 3G wireless systems, the wireless LANs, and the wireless MAN have included different modulation schemes as a means to provide a higher data rate. Based on the perceived Signal-to-Noise ratio (SNR) of the immediately previous frame in the frame exchange process, provisioning of service delivery are dynamically varied by selecting links that can use higher bandwidth modulation schemes. In this paper, we considered different images classes and different modems schemes to provide a study of the physical-layer link speed effect on high-layer network performance based on different QoS parameters that depend in class and type of multimedia traffic. In our work, we have considered basics modulation techniques used in mobile and wireless systems.
