Abstract
Satellite communication provides services to users over wide area. However, the propagation delay and the link budget associated with the long path make the communication difficult. Better link budget and smaller user antennas make high-altitude platform (HAP) based communication one of the favourite choice to last mile users over satellite connectivity. HAPs with overlapped service area form an interference limited system. To this end, interference alignment is proposed as promising solution to maximize capacity between multiple HAPs and ground stations. In this context, explicit expressions for system’s sum-rate and bit error rate (BER) are derived. The sum-rate and BER performance of the proposed scheme are studied for different Rician factors representing different geographical locations. Monte Carlo simulations are used to validate the analytical expressions.
