What sort of CPU are you using?

Not clear to me how to use them to effect non-uniformly-spaced channels.  Also, individual channels will have their own bandwidths.

See also: "Polyphase Filter Banks For Unequal Channel Bandwidths And Arbitrary Center Frequencies" by fred harris et.al..  I don't know of anyone who's implemented this yet; and, really IIRC, the complexity is absurd.  But it might work ;) - MLD

Thanks.  I did try the polyphase channelizer briefly, using a simple low-pass filter, and it provoked roughly as many 'O's as any of the other
 approaches.  I think I may need a faster CPU for handling 25Msps, no matter how I do it.
