Thanks for confirming. I believe that IT++ version will work with corresponding GNU Radio version.
Also what do you think (since you have developed the code for long time :) ) : IT++ version will be as efficient as the current one? I mean the current version uses SIMD for Viterbi. I have tested the current version for success rate. I can share the results(attached). Success rate mentioned is nothing but ratio of received to transmitted frame per second using a R&H VSG. The test was done over the air. On 18 January 2018 at 13:06, Bastian Bloessl <[email protected]> wrote: > Hi, > > you are right.
