DVB-T Pre-IFFT on OFDM Symbol ...

Started by January 3, 2006
I to write a simulator DVB-T (ex:
http://dante.diei.unipg.it/~baruffa/dvbt/cdevelop.php).
I am successful to implement the simulator until the Pre-IFFT phase
(Data + Pilot + TPS) but now I am blocked to the preparation of the
data before the IFFT (Pre-IFFT).

In that way the data must be prepare before entering in block IFFT ?

There is need to implement Hermitian Matrix ? But like ?

For the 2K modulation they are necessary 2048 IFFT point (Data + Pilot
+ TPS + Guard Interval), as I must prepare the buffer before entering
in block IFFT ?

Please help me.

Thanks Kappa.
