Energy and Spectral Efficiencies Trade-off with Filter Optimization in Multiple Access Interference-Aware
This work analyzes the optimized deployment of two resources scarcely
available in mobile multiple access systems, i.e., spectrum and energy, as well
as the impact of filter optimization in the system performance. Taking in
perspective the two conflicting metrics, throughput maximization and power
consumption minimization, the distributed energy efficiency (EE) cost function
is formulated. Furthermore, the best energy-spectral efficiencies (EE-SE)
trade-off is achieved when each node allocates exactly the power necessary to
attain the best SINR response, which guarantees the maximal EE. To demonstrate
the validity of our analysis, two low-complexity energy-spectral efficient
algorithms, based on distributed instantaneous SINR level are developed, and
the impact of single and multiuser detection filters on the EE-SE trade-off is
analyzed.Comment: 14 pages, 6 figures, 2 tables, conference pape
