Viterbi algoritms for STTC

Started by ibto75 August 18, 2009
Hi all,
Can anybody please tell me if there is any different between the viterbi
algorithm for Convoluntional code and that for Space time trellis codes.
I have tried using the decoding approach for convoluntional and trellis
coded modulation (TCM) to decode my 2 states BPSK  space time trellis code
but the ber that  is producing is quite embarasing.
Can anybody please help me out.
I am writing my code in C++.
It will be aprreciated if someone can lend a helping hand here.
