Work progresses on my software decoder

Here is another quick video of my work on using CUDA to do DVB-S2 demodulation.
I have now reached the dizzy heights of 500 Kilo Symbols per second in real time
with 20 iterations of the LDPC decoder still a long way to go and a lot to learn about
programming in CUDA.

    Hello G4GUO! Are you planning this as a commercial project or just for educational purposes? Would you consider sharing your source code? If you don't want to publish it, would you maybe consider sharing it with me, for educational purposes, i promise i will not give it to anyone. This is very important for me, i have been working on a similar thing but I have stumbled upon some problems, i would really appreciate to be able to look how someone else has done it. Thank you!

    Hello Andris, nothing I do is commercial it is all for self learning. Yes I plan to release the code when I am happy with it. Currently it is limited to low symbol rates and the preamble detection code needs a lot of work. When I have fixed those two things I will release it. It may take some time though.
