WebThe M-BCJR [ 1] is a low complexity version of the leader MAP-BCJR (Maximum A Posteriori) algorithm [ 2 ]. It consists to use only M best metrics in trellis. Others states are not evaluated next step, so the complexity is reduced. The M-BCJR finds its applications in turbo equalisation [ 3] where more variants are proposed [4-6]. WebJan 17, 2006 · MAP decoders are typically used iteratively, though, in things like Turbo Codes where the system iterates between two separate convolutional encodings of the same data (with the order of one being scrambled by an interleaver). The MAP itself is not iterative. Eric Jacobsen Minister of Algorithms, Intel Corp.
