Spatial Dynamic Spectrum Allocation and Population Density

This paper presents a summary of some results on spatial dynamic spectrum allocation (DSA), in a flexible spectrum licensing environment. A realistic population density distribution scenario in conjunction with the spatial DSA is taken into account, to mitigate the spectrum wastage in terms of extra guard band. For the insertion of the extra guard band, an efficient strategy based on self assessment is applied by the each victim cell individually and independently. Consequently, it is no more required to spread the extra guard band over the whole DSA region. Simulation results show improvement for both the considered UMTS and DVB-T networks.
