about COMPLEX_PER_SYMBOL in atx.h

    Question

  • In atx.h, the constant COMPLEX_PER_SYMBOL is defined as 160. But in IFFT, there are only 64 points. I think the length of a OFDM symbol is 80 COMPLEX8s plus GI. Who can help me? Thank you!

  • yes, it is 160. because samples in one symbol are up sampled twice yielding 160 = (2 * 16 + 2*64) samples (including up sampled GI samples)
