Turbo equalization: principles and new results

IEEE Transactions on Communications, 2002
We study the turbo equalization approach to coded data transmission over channels with intersymbol interference. In the original system invented by Douillard et al. (1995), the data are protected by a convolutional code and the receiver consists of two trellis-based detectors, one for the channel (the equalizer) and one for the code (the decoder).

Modified LMMSE turbo equalization

IEEE Communications Letters, 2004
This letter presents a modified linear minimum mean square error (LMMSE) turbo equalization scheme that uses an augmented real matrix representation for quadrature modulation systems. In the proposed scheme, the estimates of the two quadrature components of the transmitted symbol have both their individual variances and their covariance considered ...
