  • Question

  • hi, everyone,

    when I find the variable-b_energyLeast in RxContext, I don't get the meaning of it.

    "pLeast: minimum allowed energy squared rectangle 1/2 width. "

    Can anybody tell me its meaning ?

     

    thx!

  • Sorry for the misleading comments. I think you asked 2 questions.

    1. What does the function SoraEstimateEnergyScope() do?
      Answer: This function check all COMPLEX16 items in XMM0~XMM6 registries, and find the smallest square to cover them all. The 1/2 of the edge width of the sqaure is defined as energy scope.
    2. What does the variable b_energyLeast mean?
      Answer: the variable will get the 1/32 of the energy scope of 802.11b frame preamble, and it will used as a threashold to check down-sampling behavior.

    If any questions, please reply. Thanks for your querying.
