Been working on this for a few months, and just added the finishing touches. It's a high performance ADS-B receiver that can detect and correct multiple bit errors and packet collisions. The FPGA offload allows a Raspberry Pi to process samples in realtime, where as a recent i7 would not be able to keep up without the hardware offload.
I'm planning on doing a mini series explaining the MATLAB, C, and VHDL design flow behind building a high performance hardware modem. The first article can be found here, https://www.nuand.com/blog/bladerf-vhdl-ads-b-decoder/
Questions or suggestions are welcome, I would like to use them to improve my writing style and this mini series!
