Abstract :
By modeling the corresponding MIMO channel as a factor graph (FG), STBC decoder, bit interleaver and LDPC decoder can be combined together to form a larger joint factor graph (JFG). Extrinsic information transfer (EXIT) charts and bit error rate (BER) results show that the JFG enables a shuffled decoding superior to the classical serial iterative detection in performance while reducing complexity.
