Abstract:

To alleviate the extremely high area spectral efficiency requirement challenge in next generations of cellular networks, dense heterogeneous type networks where base stations transmit with different power levels are been considered operating at new frequencies in millimeter-wave (mm-Wave) band. The high density of the aforementioned networks, unfold with small area cells that even with higher attenuation of mm-Wave signals encounter inter-cell interference. In this work, heterogeneous, and homogeneous downlink cellular networks operating in mm-Wave frequencies are considered, in which all wireless channels are modeled by fluctuating two-ray (FTR); a mm-Wave channel model recently proposed, and shown to fit well with experimental data. Analytical expressions for coverage probability, average rate, and bit error probability under inter-cell interference are obtained. Simulation results show the accuracy of the analytical derivations. Moreover, in some scenarios, FTR channel model exhibits a significant performance degradation over Nakagami, and Rayleigh fading channel models. Finally, one of the auxiliary fading parameters of FTR model, defined as power of line of sight components to that of diffuse component, has the most significant effect on the system performance.
