For anyone that is remotely interested, here is the big picture for the problem I'm trying to solve. If you are not interested, hey delete the post. Won't irritate me in the least! What I'm trying to do: Optimizer for a radar power spectral density problem Problem: FFTs required in optimiza

Have you considered using a fast compression/decompression algorithm before you transmit, one that isn't too computationally intensive for either compression or decompression? You won't get high compression (factor of 10) as you might with slower ones, but if you get even a factor of 2, you've jus
