ofdm frame

Started by awi May 21, 2007
Hi friends

I have doubt in mind. I always read about OFDM frame where in each
OFDM frame consist of 2 or 1000 or ...... OFDM symbols. Why OFDM
signal is transmitted in frame format ? Why  OFDM does not transmitted
in each OFDM symbol ?

Many thanks in advances.

Regards,
Wiwi

The modulation and demodulation are usually implemented via the Fast Fourier Transform, which operates on finite chunks of data. So I guess it's natural. Julius
