Abstract
In this paper we present tests results of the first platform implementing a high performance Random Access protocol dubbed Enhanced Spread Spectrum Aloha (E-SSA), conceived for satellite applications. The aim of the study is to highlight key features of the system, introducing experimentally-found threshold values and translating them into operating conditions. A system overview is provided together with a summary of the most relevant parameters and the framework of the tests. The preamble detection and the packet demodulation processes are analysed, showing the importance of exploiting Successive Interference Cancellation techniques (SIC). It is shown that the code collision, due to a robust rate in the turbo-code and to the iterative cancellations, does not affect the system performances. Finally, Packet Loss Ratio (PLR) in presence of received carrier power and frequency unbalance is detailed with the aim of simulating more realistic scenarios.
