Hi,

Suppose we have aperiodic sequence \[x[n]\], and we process it to make it periodic sequence \[\tilde{x}[n]\] with period P, and we transmit this periodic sequence over a wireless channel. To apply DFT at the receiver, would it be possible to do that after dropping the added samples to \[x[n]\] that made it \[\tilde{x}[n]\], or we must maintain these samples and drop them later after we are done from the DFT process?

Thanks
