Braided convolutional codes
Wei Zhang, Michael Lentmaier, Daniel J. Costello, Kamil Sh. Zigangirov · 2005
We present a new class of iteratively decodable turbo-like codes, called braided convolutional codes. Constructions and encoding procedures for tightly and sparsely braided codes are introduced. Sparsely braided codes exhibit good convergence behavior with iterative decoding, and a statistical analysis using Markov permutors shows that the free distance of these codes grows linearly with constraint length.
