Differences between sub1g and openwifi modulation modes #376

Closed s-zhen66 closed 1 week ago

s-zhen66 commented 7 months ago

Hello, Dr. Jiao,

I would like to ask you:

  1. What is the difference between modulation and demodulation of sub1g and openwifi?
  2. According to the protocol, the modulation mode of 2M channel bandwidth of sub1g is the same as that of 20M channel, but the clock rate is 1/10.Is the clock rate here the duration of ofdm? Can openwifi's OFDM be directly used in this way? Do I need to make any other changes?

Thank you and look forward to your reply.
