In order to mitigate inter-cell interference and cope with network, traffic, and channel fluctuations in space and time, Orthogonal Frequency Division Multiple Access (OFDMA) based cellular networks should be equipped with dynamic frequency and power allocation algorithms. Although dynamic frequency and power allocation has been well studied separately, very few results have been reported on dynamic...
This work presents 2 novel approaches for the self-organization of Orthogonal Frequency Division Multiple Access (OFDMA) femtocells, in which the femtocell is able to dynamically sense the air interface and tune its sub-channel allocation in order to reduce inter-cell interference and enhance system capacity. In the sensing phase, these techniques make use of either messages broadcast by the femtocells...
The PowerPoint presentation work has introduced a novel dynamic frequency planning approach to the frequency assignment problem tailored to OFDMA networks. DFP may decrease the inter-cell interference and increase the capacity of the network by dynamically adapting the radio frequency parameters to the specific scenario. DFP uses novel algorithms to sense the radio channel, and adapted versions of...
