ITERATIVE SOVA DECODING OVER SYMMETRIC ALPHA STABLE CHANNELS [PDF]
Journal of Engineering Science and Technology, 2012 Soft-Output Viterbi Algorithm (SOVA) is one type of recovery memory-less Markov Chain and is used widely to decode convolutional codes. Fundamentally, conventional SOVA is designed on the basis of Maximum A-Posteriori probability (MAP) under Additive ...
