Dynamic Artifice Appropriation in OFDM Systems: An Overview of Cross-Layer Optimization Principles and Techniques

Recently, a lot of research effort has been spent on cross-layer system design. It has been shown that cross-layer mechanisms (i.e. policies) potentially provide significant performance gains for various systems. In this paper, the authors review several aspects of cross-layer system optimization regarding wireless OFDM systems. They discuss basic optimization models and present selected heuristic approaches realizing cross-layer policies by the means of dynamic artifice appropriation. Two specific areas are treated separately: models and dynamic approaches for single transmitter/receiver pairs - i.e. a point-to-point communication scenario - as well as models and approaches for point-to-multi-point communication scenarios - such as the down-link of a wireless cell.
