Turbo synchronization: an EM algorithm interpretation
Nele Noels,Cédric Herzet,A. Dejonghe,Vincenzo Lottici,Heidi Steendam,Marc Moeneclaey,Marco Luise,Luc Vandendorpe +7 more

TL;DR: It is shown how maximum-likelihood estimation of those synchronization parameters can be implemented by means of the iterative expectation-maximization (EM) algorithm, and how the EM algorithm iterations can be combined with those of a turbo receiver, leading to a general theoretical framework for turbo synchronization.
Turbo-equalization for multilevel modulation: an efficient low-complexity scheme

- 07 Aug 2002
TL;DR: Reduced-complexity soft-in/soft-out (SISO) equalizers based on the minimum mean square error (MMSE) criterion (originally proposed in a BPSK context) are generalized to solve the problem of iterative equalization and decoding when bit-interleaved multilevel modulations are considered.

A theoretical framework for soft-information-based synchronization in iterative (Turbo) receivers

TL;DR: The aim of this paper is to show that such "turbo-estimation" approach can be regarded as a special case of the expectation-maximization (EM) algorithm and lead to a general theoretical framework for turbo synchronization that allows to derive parameter estimation procedures for carrier phase and frequency offset, as well as for timing offset and signal amplitude.
MMSE turbo receiver for space-frequency bit-interleaved coded OFDM
D. Zuyderhoff,X. Wautelet,A. Dejonghe,Luc Vandendorpe +3 more
- 01 Jan 2003
TL;DR: This paper considers transmission of OFDM modulated signals over MIMO frequency-selective fading channels using a set of low-complexity MMSE SISO equalizers, achieving both spatial-interference mitigation and demodulation.

A comparison of bit and symbol interleaving in MMSE turbo-equalization
A. Dejonghe,Luc Vandendorpe +1 more
- 11 May 2003
TL;DR: It is shown that bit- interleaved TE with carefully chosen constellation mapping and proper implementation can outperform its symbol-interleaved counterpart, and efficient low-complexity MMSE-based implementations are proposed.
