The cpp file you are using is not included in the archive from MATLAB central. C_SISOrsc.cpp uses algorithms now included into IT++ library. You should either install IT++ library before trying to compile that file, or customize yourself SOVA implementation in order to become independent from IT++.

R is the rate of the turbo code, which has a rate of 1/3 when there is no puncturing pattern

Could you provide a simulation with multipath channels ?

11 Oct 2009 Soft Input Soft Output Viterbi Algorithm Implementation of the SISO Viterbi algorithm. Author: Adrian Bohdanowicz

Useful code, however I have some doubts about its correctness. When the transition metric in computed, the AWGN noise variance is not taken into account, while the code rate is used. This seems to me wrong.

26 Aug 2009 Log MAP decoder Log MAP decoder for feedforward & feedback convolutional codes Author: Hari Moorthy

- This implementation is not well suited for turbo decoding since the function input is the channel output. I would suggest to modify the function inputs in order to accept directly some LLRs. Thus the last parameters, Lc, shall be no longer needed.
- I would like to have an option for using terminated or unterminated trellis
- The code also should be cleaned

12 Dec 2013 txtprogressbar show simulation progress and remaining time as text Author: Bogdan Cristea kasim tasdemir

Hi,

I use 'dispstat' function just for this purpose. It can update the previous output which is a missing function of default 'disp'. Very simple to use. It can be downloaded from here: http://www.mathworks.com/matlabcentral/fileexchange/44673

***Sample usage:
dispstat('','init'); % One time only initialization
dispstat(sprintf('Begining the process...'),'keepthis','timestamp');
for i = 97:100
dispstat(sprintf('Progress %d%%',i),'timestamp');
%doing some heavy stuff here
end
dispstat('Finished.','keepprev');

***Output:
11:25:37 Begining the process...
11:25:37 Progress 100%
Finished.

All the best
