For a OFDM signal, after DAC with 12.5Gsa/s sampling rate, what is the bandwith? How to calculate?
If the OFDM signal with Hermitian symmetry, what is the bandwith? The Hermitian symmetry will reduce the bandwith?
For a OFDM signal with DAC sampling rate of 12.5Gsa/s, after ADC with 25Gsa/s, what is the bandwith? After down converter, what is the bandwith?
I'm very confused by the bandwith calcluation of the OFDM signal? How to calcluate the bandwith?
