To create a OFDM based modulator using QAM-64 and inverse FFT. How often must the inverse FFT calculation be run to produce the appropriate amount data to send to D/A?
And how fast should the D/A be run?

IFFT size: 8192 point
Symbol period: 1194.667 µs
Carriers: 6817
Modulation: OFDM with QAM-64 subcarriers
Bandwidth: 8 MHz
Useful bitrate: 22.118 Mbit/s
