- This paper studies the sum throughput of the returnlinkin multi-beam satellite systems. Considering bursty communication scenarios with different users’ data request probabilities, we develop an efficient scheduling scheme using genetic algorithms (GAs). The results are obtained in different cases with and without successive interference cancellation at the receiver. Moreover,we evaluate the effect of adjacent channel interference (ACI) and co-channel interference (CCI) on the performance of the scheduler-based satellite systems. As demonstrated, the proposed GA-based scheduler reaches (almost) the same throughput as the exhaustive search-based optimal scheduler, with substantially lessimplementation complexity. Moreover, the throughput becomes insensitive to the ACI and substantial performance improvements are achieved if successive interference cancellation is utilized by the receiver.
