Analytical evaluation of cell structure based on a 19-cell network

The study aimed to investigate whether distinct cellular network structures would result in different performances for specific spectrum distribution methodology and find the optimal structure for a 19-cell wireless system. Based on the hybrid spectrum allocation involving Simultaneous Water-Filling (SWF) and Fraction Frequency Reuse (FFR), we proposed four structures. Furthermore, the comparison of their channel capacity was made based on the hybrid spectrum allocation involving SWF and FFR algorithm. The consistency of the methodology was maintained by considering the distance-based path loss and the intercell interference for channel transmission. Both numerical and analytic results were validated to prove that the most cell-scattered network structure had the best performance, with a maximum 30% improvement to the others. In addition, the research also certified that the FFR algorithm could use the spectral resource thoroughly to optimize the channel capacity to a large extent.
