This paper introduces a coevolutionary approach to genetic algorithms (GAs) for exploring not only wihtin a part of the solution space defined by the genotype-phenotype map but also the map itself. In canonical GAs with the fixed map, how large area of the solution space can be covered by possible genomes and consequently how better solutions can be found(More)
This paper addresses the problem of fair radio resource partitioning between the cell-edge and cell-center regions in the context of the downlink of a SISO-OFDMA cellular system. Although, a plethora of studies concerning OFDMA-based radio resource allocation exists, it is, however, imperative to accord special attention to the proper design of network(More)
Femtocell is an emerging technology that promises increased network capacity and enhanced indoor coverage at a low capital and operational cost. However, macrocell network performance depreciates when macrocell users (mUEs) are located indoors with femtocell base stations (FBSs), and these users are not allowed access to the FBSs (closed access). This is a(More)
