Özet:

 


In this study, the energy-efficiency (EE) problem is investigated for
downlink Orthogonal Frequency Division Multiple Access (OFDMA) cellular
networks. The EE maximization problem is defined under certain
prescribed per-user quality-of-service (QoS) demands and maximum system power
limit. EE metric that aims to maximize the system data rate and minimize the
total power consumption at the same time is used as the objective function of
the defined problem. In this form the optimization problem belongs to a broad
class of problems called mixed-integer non-linear programming problem (MINLP),
that is difficult to solve in its original form in such a multi-carrier,
multi-user networks. Hence, we have decomposed the original problem into two
parts and presented a solution that performs subchannel allocation and power
allocation parts separately. Simulation
results are obtained to confirm the performance of the presented scheme in
terms of energy-efficiency and total data rate.
