Thank you for the excellent presentation. Maybe I missed that part, but how do we lock to the incoming data packet frequency, so that sampling begins more or less at the start of the packet?
Why do we need to copy. Why can't we just generate the 80 samples directly from the IDFT? That should yield the exact same result. No? What did I miss?
Why is CP length of 800ns not sufficient to combat delay spread of 200ns(leaving a residual in the next symbol in example shown)? What is the relationship between relation between minimum CP length required given a doppler spread?

Perfect explanation

Same question. My guess they want to save DDS resources generating those extra 16 sine points
Who is Si DSP corp? A virtual mom and pop operation?
