Performance Analysis of Frequency Reuse for PPP Networks in Composite Rayleigh-Lognormal Fading Channel

Fractional frequency reuse (FFR) is an effective intercell interference coordination technique that mitigates intercell interference and improves users' performance, especially who suffer low signal-to-interference-noise ratios. To examine the performance of FFR algorithms, a Poisson point process network model in which base stations and users are distributed as a Poisson process has been recently developed to replace the traditional grid model. The average coverage probability of a typical user that connects to the closest base station, however, is only considered in Raleigh fading and then its closed-form is only found in case of high transmission signal-to-noise (SNR) or neglecting noise. This paper focuses on deriving a closed-form expression for the average network coverage probability in composite Rayleigh-Lognormal for both low and high SNR.
