Hey Guys,
I wrote a blind turbo equaliser for LDPC encoded data a few years ago in
GNU Radio, the code is probably pretty horrific, and it wasn't optimised
very well, but it worked as a proof on concept, I could dig out the code if
anyone was interested?

Hey Nguyen Anh Duc,
thanks for your input. It's nice to see that there seems to be some guys
interested in the whole turbo EQ topic. These are some interesting
points you mentioned. To be honest i never thought about using MLSE/MAP
for the equalizer part. Same goes with another turbo decoder
Dear Jan Krämer,
I am very interested in your proposal. However, to my best of knowledge,
turbo equalizer (TB) is pretty complicated and computationally heavy, then
it is challenging to have an effective real-time implementation of TB. I
would like to have some questions as follows:
1. Your ISI

Hi everyone,
I am a student at Communications Engineering Lab (CEL) at Karlsruhe
Institute of Technology. I major in communication systems and I am
currently doing my masterthesis on Parallel log-map decoders for
manycore architectures. I am interested in participating in GSoC 2014.

Yes, I agree with Tom.
A good starting point is the three or four core algorithms in
gr-trellis/lib/core_algorithms.cc
viterbi_algorithm,
siso_algorithm,
sccc_decoder
pccc_decoder
(and their _combined versions)
Jan, let me know if you decide to work on these; I can provide
some ideas if you are

I know I could look to Google / do an internet search, but maybe asking here
would be better.What is/are the -seminal- paper/s on parallel log-map-siso
decoding?
I implemented the non-parallel version of the log-map algorithm -way- back in
2001 on whatever the portable Mac was at the time
Mike,
there are roughly 3 ways you can parallelize these algorithms:
1) packet-level: run a lot of codewords at the same time
2) subblock level: divide each codeword into pieces (overlapping) and run
SISOs on each one of them in parallel
3) trellis level: do ACS operations in parallel
