Abstract

Practical linear precoding methods are proposed for High Throughput GEO Satellite systems operating in the Ka band for DVB-S2 communications. The main focus is on implementation issues relevant to multiuser DVB-S2 frames. Since different users must be addressed by the same precoding matrix at the transmitter, the standard precoding algorithms do not apply directly but need to be adapted. Geographic user clustering is proposed to take this into account. Additional implementation constraints are accounted for, including CSIR estimation, outdated CSIT, and oscillator phase noise. Numerical results are presented to illustrate the system trade-offs and the achievable throughput gains available from linear precoding.
