This work describes an interference study of the return link (user terminals to gateways) of a high throughput satellite (HTS) for broadband services. The aim is to identify a statistical behavior of the inter-spot interferences due to frequency re-use so as to estimate the carrier over interference ratio (C/I) on the uplink segment of the return link for a multi frequency time division multiple access (MF-TDMA) technique. The characterization of the interference will be done based on a mathematical model and validated through empirical observations for different transmission scenarios and satellite systems. In this work, we use the C/I performance at satellite antenna level as a benchmark parameter, in order to find the most faithful statistical law for the generated interferences. The satellite architecture itself uses a multi-beam coverage implementing frequency re-use and spatial separation.
