Objective • Propose a modulation for the low data rate option (nominal 100 kbps) which is built the same way than for the other rates L. Ouvry — CEA-Leti
Mandatory Mode Modulation & Coding(from 681r0) L. Ouvry — CEA-Leti
Modulation L. Ouvry — CEA-Leti
Reed Solomon Primitive polynomial: Generator polynomial: Coding L. Ouvry — CEA-Leti
Optional low bit rate Mode • Same approach than for optional higher rates : • Increase symbol duration • Proportionally increase number of pulses in the burst to keep mean PRF constant L. Ouvry — CEA-Leti
Modulation & Coding options L. Ouvry — CEA-Leti
Conclusions • Proposal for a modulation scheme suitable for the nominal ~100 kbps option • Built straightforwardly from the other bit rate modes • Suitable for the coherent receiver • Suitable for the non coherent receiver L. Ouvry — CEA-Leti
