Throughput performance of Globalstar Low Earth Orbit (LEO) satellite system is considered. The effect of Multiple Access Interference (MAI) on throughput performance of a direct sequence spread spectrum LEO satellite communications network is discussed under non-uniform traffic model. Both Dense Traffic Satellite (DTS) and Sparse Traffic Satellite (STS) throughput are calculated. Finally we compare the normalized throughputs of both DTS and STS

We consider one LEO CDMA satellite system that consists of 48 satellites running in 8 orbits, each contains 6 satellites. The system is at height 1400 Km from the Earth surface. The performance criteria are the Signal-to-Interference ratio (SIR). Both Dense Traffic Satellite (DTS) and Sparse Traffic Satellite (STS) are considered.
