Abstract EN
Energy efficiency (EE) capacity analysis of the chunk-based resource allocation is presentedby considering the minimum spectrum efficiency (SE) constraint in downlink multiuser orthogonal frequencydivision multiplexing (OFDM) systems.
Considering the minimum SE requirement, an optimization problemto maximize EE with limited transmit power is formulated over frequency selective channels.
Based on thismodel, a low-complexity energy efficient resource allocation is proposed.
The effects of system parameters,such as the average channel gain-to-noise ratio (CNR) and the number of subcarriers per chunk, are evaluated.
Numerical results demonstrate the effectiveness of the proposed scheme for balancing the EE and SE.
