Resource allocation method for improved energy efficiency in mimo -ofdm wireless systems

Abstract

In the past several researches , various Antenna Selection Strategies for MIMO-OFDM wireless Systems is investigated based on Energy Efficiency  perspective . In  Adaptive Method there is a Significant loss in the Energy Efficiency and Energy Efficiency(EE)-Spectral Efficiency(SE) Trade-Off.

To achieve a better Energy Efficiency, Based on the practical model we investigate Resource Allocation Task .It is formulated as an optimization problem that aims at maximizing the weighted sum-rate of MIMO Broadcast channels . We are witnessing a paradigm shift from Throughput optimization to Energy Efficiency optimization methods and the Fractional Programming Theory concerned with Optimization and Properties of Fractional Functions to improve Energy Efficiency over  Traditional Resource Allocation Schemes.Resource Allocation include effectively setting up equipment  and operations and about increasing profits and Productivity While minimizing Resource Wastage.
