Hey guys,

I finally finished a first draft of my proposal for GSoC 2014 on  
improvements for gr-trellis and a turboeq block.  
It’s available on github:

[https://github.com/SpectreJan/GSoC2014](https://github.com/SpectreJan/GSoC2014)

Please let me know what you think of it.

Best regards,  
Jan

“Adjust qa\_trellis.py if necessary. Implementing VOLK library. Test for  
quality and benchmark for speed.”

It seems like you have something specific in mind, but “implementing  
VOLK library” is ambiguous. Can you be more specific here?

Also, can we see some of your previous work?

In general, very good proposal. But get rid of the typos if you want me  
on your side 😃

Sounds goods. He has made up some thoughts about it and is driven to  
accomplish his goals. i would give him a try 🙂 (i didn’t see any typos  
btw)

and don’t forget: it’s for his studies 😉

Hey,

thanks for the advice. Though I’m a bit bummed about the typos. Checked  
it  
multiple times using a grammar/spell checker.

And yes, I already have thought about some tasks in both SISO and  
Viterbi  
algorithm that could be accelerated by VOLK. Mainly final output  
calculations and the calculation of the transition probabilities as both  
of them are data parallel tasks.  
I will update my proposal accordingly tomorrow.

best regards,  
Jan

Hey,

an updated version of my GSoC proposal is now on available:

[https://github.com/SpectreJan/GSoC2014](https://github.com/SpectreJan/GSoC2014)

Regarding work that I have done in the past:  
Parts of the code of my current master thesis project (Log-MAP decoder  
with OpenCL) is now available on Github.

[https://github.com/SpectreJan/cel\_gpu\_logmap](https://github.com/SpectreJan/cel_gpu_logmap)  
This is also included in my proposal.

I also have done some work on getting a non-proprietary linux  
distribution  
on the Lyrtech SFF-SDR. A small compendium is available on the  
Communication Engineering Lab website. But it is in German, as it was  
initially meant as a CEL intern manual only. But maybe Phil might enjoy  
this 😉
