Soft-In Soft-Out DFE and Bi-Directional DFE
2011
IEEE Transactions on Communications
Preserved Fulltext
We design a soft-in soft-out (SISO) decision feedback equalizer (DFE) that performs better than its linear counterpart in turbo equalizer (TE) setting. ...
We also describe a new extrinsic information combining strategy involving the outputs of two DFEs running in opposite directions, that explores error correlation between the two sets of DFE outputs. ...
Powerful modern equalization methods are based on the turbo equalization principle established in [1] , wherein a soft-in soft-out (SISO) equalizer (or detector) and a SISO error-correction decoder exchange ...
