Rotated Constellations for a Satellite Communication Link in a DVB-T2 context

Résumé

In this paper, the focus is on DVB-T2-like rotated constellations techniques applied to a satellite link for mobile services. Associated with signal space component interleaving, a QPSK constellation with rotation is evaluated over S-band satellite mobile channel with payload impairments. Channel capacity is first assessed showing an important potential for improvement. Largest gains are obtained for high spectral efficiency and for the cases with high level of impairments. Coded simulations show that rotated constellation can bring up to 1.5 dB gain for medium to high coding rates over a satellite to vehicle channel, confirming channel capacity predictions.
