Abstract :
In this paper the uplink performance of delivering WiMAX broadband via high altitude platforms (HAPs) cellular system is evaluated and the coexistence capability with terrestrial WiMAX operators is assessed. A coexistence scenario of a HAP and terrestrial WiMAX base stations deployed inside a HAP coverage area with a radius at 30 km will be proposed. A HAP cellular formation with different reuse patterns and multiple antenna payloads will be established. Coexistence performance will be assessed in terms of uplink signal to HAP interfered by terrestrial system and vice versa. Simulation results show that the two systems can share the spectrum effectively.
