In this paper we analyze an OFDMA cellular system , whose resource allocation scheme is Soft Frequency Reuse (SFR). We focused our work on defining how to select some of the system operation parameters that guarantee a trade-off between efficiency in the use of the resources and fairness in the distribution of them. Specifically, we developed a mat...

... the symmetry of the interference sources, our selected reference radial line has an orientation of 60 0 from the horizontal, as it is shown in Fig. FIGURA2. Since the distance loss exponent has a large value in urban environments, we only calculate the interference from the firs ring. Under this assumptions, the SINR in terms of r is given ...

... our simulation we consider that users arrive to the system following a Poisson process of λ intensity. Each arriving user is randomly assigned to one of the seven cells that are illustrated in Fig. 1 and its position in that cell is uniform and randomly selected. As it is shown in Fig. 2, the user of interest is classified as center or edge user, depending on its path loss. Once that the user region has been identified, if there are available channels in the corresponding set, one of them is randomly assigned to the user of interest (we denote it as channel u). After that, the user initiates a 2.52 Mbytes file download ...
