Abstract:
|
Nowadays mobile operators are planning and de-
signing their mid/long term strategies based on new OFDMA-
based cellular technologies such as LTE and WiMAX. Co-siting
and re-utilization of existing facilities are within their roadmap
in order to keep CAPEX as low as possible. Therefore, the
optimization of OFDMA networks subject to fixed/previous (and
usually suboptimal) coverage is mandatory. In addition, recently
there is a great interest in reducing OPEX mainly by means
of energy savings. This paper presents a novel multiobjective
formulation aiming at improving the performance of OFDMA
networks where full frequency reuse is employed. The proposed
framework is flexible and results indicate that it is also effective
as it improves both spectral efficiency and cell edge performance
while it simultaneously reduces energy consumption. |
