This talk is aimed at giving an update on my efforts to open source my CUDA Polyphase Filterbank library DLR-CAFE, the Satellite Networks Department Coprocessor Accelerated Filterbank Extension Library, developed at the German Aerospace Centre (DLR). It will contain a short introduction to the newest addition to the library, a Polyphase Filterbank Arbitrary Resampler. Following this, I will give a brief update on my progress to release the library into the Open Source wilderness.
