In this paper, the uplink capacity of a cellular code division multiple access system is improved by using two high altitude platform stations (HAPSs). By considering a practical shadowing model, uplink capacity is numerically analyzed, and it is shown that the capacity can significantly be improved when two HAPSs are used, as compared to that of a single HAPS system.
