High Throughput Satellite (HTS) systems exploting frequency reuse via multi spot-beam transmission is one of the key enablers for delivering high data-rate broadband services. However, such systems are prone to co-channel interference (CCI) and technological limitations surrounding the generation and deployment of small spot-beam sizes. Therefore, interference mitigation techniques (IMT) are employed to combat the effect of CCI and to improve system performance. In this context, we investigate linear and nonlinear precoding schemes as interference mitigation tools on the forward downlink of a multi spot-beam satellite under practical operating conditions. The simulation results have shown a gain in system performance, where non-linear precoding techniques outperform their linear counterparts. An investigative study exploiting the joint application of spreading with the proposed precoding schemes is also reported.
