Hi STeve
the filter is great but in practice you are unlikely to do better than
about -30dB for the 'sidebands' (intermods) without careful linearization.

I've been working some more on my Java OFDM version:

I could not get the new DFT code to work with it though. It just
created a mess, so I went back to the old way, seeing how Java DSP is
not for microcontrollers anyway :-)
One thing I was interested in was the FIR filter, and it looks like
the filter is doing quite an amazing job. I kept the picture size
small for email, but the top spectrum sidebands are down about 60 dB
on the top, and 90 dB on the bottom. Pretty clean.
Happy New Years to all,
Steve
