Impact of Resource Blocks Allocation Strategies on Downlink Interference and SIR Distributions in LTE Networks: A Stochastic Geometry Approach

Figure 3

Interference distribution: empirical (histogram) and extrapolation (curve). Among the classical distributions, the best extrapolations are Gamma (m=10.03, var=9.77), normal (m=28.23, var=22.16), and Weibull (a=25.14,b=5.75) for the heuristic, MMRB allocation and static allocation , respectively.

(a) Heuristic, = 3

(b) allocation, = 6

(c) Static allocation, = 9
