I've been working some more on my Java OFDM version: Java OFDM <https://github.com/srsampson/SmallDV/tree/master/java>
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 [image: spectrum.png]
