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

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
