Multiuser precoding of the linear kind is one of the most promising candidate techniques required for managing inter-beam co-channel interference in aggressive frequency re-use multibeam High Throughput Satellite (HTS) systems. Although academic research on precoding schemes for broadband interactive satellite communication (SatCom) systems is intensifying, there are a number of practical constraints in current DVB-S2-based HTS systems that may inhibit the application of precoding. These have not been dealt with hitherto in the literature. The present article attempts to list the relevant issues, propose some possible ways forward and present some preliminary simulation results.
