Iterative Symbol-by-symbol Decision Feedback Detection for MIMO-ISI Channels
APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006 This paper investigates the decision feedback detection for intersymbol interference multiple-input multiple-output (MIMO-ISI) channels. Firstly, a constrained symbol-by-symbol decision feedback detector (CS-DFD) is presented, in which a fixed constraint is used to mitigate the error propagation.

Optimal Symbol-by-Symbol Detection for Duobinary Signaling [PDF]
IEEE Transactions on Communications, 1983 An optimal symbol-by-symbol detection scheme for duobinary signaling (Class I PRS) which exploits the inherent correlation properties of partial response signaling (PRS) is postulated. Analytical results indicate a maximum improvement of approximately 0.7 dB over conventional split shaping duobinary detection at a 10-4error rate.

Detection with embedded known symbols: optimal symbol placement and equalization [PDF]
2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002 The detection of a data sequence with embedded known symbols is considered. For a class of symbol-by-symbol decision feedback receivers, known symbol distributions optimal with respect to the criterion of average mean square error (A-MSE) are presented. Optimal design of the decision feedback receiver is also obtained.
