Abstract

ABSTRACT
The TDMA-Iridium and the CDMA GlobalStar are two of the main LEO satellite systems. Since the trend is towards CDMA due to its valuable advantages, a version of the TDMA-Iridium namely CDMA-Iridium is proposed. A comparison between GlobalStar and the proposed system is performed concerning the signal- to-interference ratio (SIR), the throughput of the Dense Traffic Satellite (DTS) and Sparse Traffic Satellite (STS) are considered. Adaptive Transmit Permission Control (ATPC) method is used to improve the throughput for both systems.
