Hi Bo,
Can you please help to revise the text of SP #1 to read as follows?
SP #1: Do you agree to add the following text into the 802.11bp SFD?
- 11bp recommends one carrier waveform for bistatic backscatter that would be based on the following 64 carrier 20 MHz OFDM symbol.
- L[i] =[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-1,1,1,-1,-1,1,1,-1,-1,-1,1,1,-1,-1,-1,1,0,1,-1,-1,-1,1,-1,1,-1,-1,-1,-1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
- where L contains carriers with indices i ∈ {-32…31} and i = 0 is the DC carrier.
- For the case where the excitation signal is sent on the lower channel, use this waveform.
- For the case where the excitation signal is sent on the upper channel, reverse the order of carriers i ∈ {-32…31}.
- Note: Following Motion #39, the carrier waveform would consist of the repeated base waveform, multiplied by a pseudo-random phase.
- Note: This waveform is recommended for use in the excitation for bistatic backscatter. Its use in other fields is TBD.
