Abstract

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.
