@baljit: I have not done MSK decoding the Viterbi way, however by using two symbols for demodulation, got comparable performance to BPSK. http://www.dsplog.com/2009/06/16/msk-transmitter-receiver/ Hope this helps.

Try to use Component-Pascal (http://www.oberon.ch/blackbox.html) I use this family of languages since more than 15 years, easy to learn, clean, safe, strong typing, fast compilation, run time type check, no dangling pointers, etc
In my opinion one of the best choices to scientific programing.

@Oluwafemi: Sorry, I have not discussed space time trellis code.

@Victor: Well, there should not be much difference… can it be some problem with the rand() number generation?

Hi Krishna Sankar,
Do you have any code in C++ for Viterbi algorithm for Space Time Trellis Code?
Please if you do, kindly help me with it?
Thank you.

Thanks for this awesome tutorial and sample code. 1 question thou: How come when I simulate the results, the soft decision BER is different as shown on this page? Around 0.49 for 0-9 dB.
