Re: [Discuss-gnuradio] GPU accelerated Viterbi decoder?

[Dan CaJacob]

What data rates are you working at?  I haven't had so much trouble with Viterbi being a limiting factor up to about 1 Mbps QPSK with concatenated coding.

Sadly, I have no experience moving this to GPU.

Dera All,
 In almost all cases the Viterbi decoder block eats a lot of CPU time. The
best alternative is a GPU solution. I have searched for an open source GPU
implementation but could not find one. There is a MATLAB implementation but
that one is far from open source.
Any Ideas? Is it easy to port gr-fec to a CUDA/ openCL based platform?
Thanks
