QoS-based AMC and dynamic SINR margin scheduling in wireless multimedia transmission systems

Abstract

This paper presents the performance of scheduling for adaptive modulation and coding based on the dynamic margin control. To cover various wireless channel conditions and requirements for multimedia traffic QoS, the selection of suitable MCS (Modulation and Coding Scheme) is important technique in real deployment and management fields. In this paper, we propose dynamic margin control schemes based on feedback information and measurement values without some efforts for optimizing additional parameters for the algorithm. Compared with existing algorithms, simulation results show that the proposed scheme is well adapted to dynamically change in the radio environment, while ensuring the QoS performance.
