Abstract :
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 simulated annealing, tabu search, or greedy algorithms to solve the optimization problem.
