Time OFDM Signal Question

Started by Unknown February 26, 2008
Hi All,

I have a simple question that hope someone can explain it. What would
be the time domain OFDM signal if you increase or decrease the number
of data tones/subcarriers e.g. increase from 135 to 220 data
subcarriers? Why this change is observed?

Thank you

Regards,
Suterr
