Whitepaper: Dynamic Resource Allocation in OFDM Systems: An Overview of Cross-Layer Optimization Principles and Techniques

by Telecommunication Networks GroupJan 01, 2008

It has been shown that cross-layer mechanisms (i.e. policies) potentially provide significant performance gains for various systems. This paper from Telecommunication Networks Group review several aspects of cross-layer system optimization regarding wireless OFDM (Orthogonal Frequency Division Multiplexing) systems. The paper discusses basic optimization models and present selected heuristic approaches realizing cross-layer policies by the means of dynamic resource allocation. Two specific areas
