Abstract :
This paper describes an extensive study into the error rate performance and channel efficiency of a TDMA mobile cellular system based on intermediate circular orbit (ICO) satellites, operating over fading channels. The aim was to investigate the feasibility of adaptive interference suppression to allow reduced channel frequency separation and thus increase total system capacity. The goal was achieved for some specific system configurations. The study investigates the performance of the adaptive receiver with various combinations of coding, channel frequency spacing, and interference scenarios
