Capacity Of Multicell Coverage Mimo Systems Analysis In High Altitude Platform (Hap) Channels

Recent studies on the capacity of multiple-input-multiple-output (MIMO) channels have focused on the effect of spatial correlation. This paper is presenting a comparative study between the performances of conventional terrestrial multicell Multiple Input Multiple Output (MIMO) working in a Rayleigh fading environment and its corresponding High Altitude Platform (HAP) system working under a different Path Loss (PL) model with the capacity as the performance metric of interest, calculated using the Singular Value Decomposition (SVD). The theoretical cases are shown to be accurate by comparison with simulation results, both systems are assumed to be affected by cochannel interference users in other cells. Simulation results show that the performance of multicell MIMO HAP dependent system outperforms its corresponding that works in terrestrial environment in terms of per user channel capacity.
