Trends in Adaptive Modulation and Coding

Free registration required

Executive Summary

This paper presents a review of techniques proposed in the literature that target the best use of resources available in a wireless communication system. These are referred to as Adaptive Modulation and Coding (AMC) techniques. A brief overview of fundamental communication limits, in particular channel capacity, is also provided in order to establish the limits for any adaptation algorithm. Furthermore, an appropriately chosen example is presented in order to demonstrate the usefulness of accurate performance modeling in the AMC design. Finally, challenges and future problems are mentioned.
