On Soft-Input Soft-Output Decoding Using “Box and Match” Techniques
Philippa A. Martin, A. Valembois, M.P.C. Fossorier, Desmond P. Taylor · IEEE Transactions on Communications · 2004
The box and match decoding algorithm (BMA) significantly reduces the computational complexity of the ordered statistic decoding algorithm at the expense of increased memory requirements. A soft-input/soft-output version of the BMA is developed. Additional complexity-reduction techniques are also described.
