Nettet12. jul. 2024 · Per definition of how OFDM works, you take a vector of input symbols, and interpret them as parallel sub carrier data. You then do an N-IDFT. That directly says the length of a symbol on a subcarrier is N samples. Always. Of course, there might be cyclic prefixing, which increases the length of the OFDM symbol further.
