Decoding multiple carriers

I have gotten some code working now to a proof of concept level. What it does is: A) Capture 2 MHz of spectrum to fifo (1) (gnuradio-companion) B) Frequency shift, filter and decimate fifo(1) -> fifo(2) using GPU C) Demodulate fifo (2) into bits to fifo(3) using my own "dodgy demodulator" D) Running tetra-rx from fifo(3) - for display in wireshark This runs realtime at around 30% CPU load (for a single core) and 30% GPU load on an ATI 5850 card. So I can easily add more carriers to tetra-rx (I have 2 such GPUs), but tetra-rx doesn't seem well prepared for handling such situations, for instance the GSMTAP packets are not tagged by ARFCN - besides I don't have a good understanding of what others would want to do when demodulating multiple carriers. Personally I have to limit myself to traffic analysis on a fully encrypted network. Are there any plans for how to progress tetra-rx that I can follow, or should I just rip the thing apart and make it do what I want it to do ? f
