I'm having some problems seeing posts lately.
Is that this NG or my ISP? I cannot see the
original post anymore.
Parallel implementing of OFDM? Some steps have to
be sequential so they could be pipelined, not done
in parallel. Depending on what you call parallel,
it is not uncommon to break up FFT/IFFTs to gain
processing efficiencies. Do a google search on
something like "butterfly fft" and you should find
something on rad 4 butterflys. You can break
a large FFT into smaller FFTs that could be done
faster. But unless you can spread those to other
processors or hardware you'll still end up doing
them sequentially (but faster).
Naturally you can do it in hardware or software, it
just depends on the speed required and the type of
processor available. DSP processors are obviously
designed for these type of operations. For really heavy
duty processing there is also dedicated FFT/IFFT processors.
Can you give any more information on what your requirements
are? Data rates, bandwidth, etc.
The NG comp.dsp would have some expertise too.
