Capacity of multiple HAP system employing multiple polarizations

In this paper we investigate the potential increase in capacity of HAP (High Altitude Platforms) communication systems using compact MIMO antenna array configurations in conjunction with HAP diversity techniques. In addition, we evaluate the system performance for different separation angles between HAPs. Simulation results show that the HAP diversity system provides superior performance compared to the single HAP case.
