Turbo-Equalization Using Partial Gaussian Approximation [PDF]
IEEE Signal Processing Letters, vol. 23, No. 9, pp. 1216 -1220,
Sept. 2016, 2016 This paper deals with turbo-equalization for coded data transmission over intersymbol interference (ISI) channels. We propose a message-passing algorithm that uses the expectation-propagation rule to convert messages passed from the demodulator-decoder to the equalizer and computes messages returned by the equalizer by using a partial Gaussian ...

The Error-Pattern-Correcting Turbo Equalizer [PDF]
Alhussien, H.; Moon, J.; , "The Error-Pattern-Correcting Turbo
Equalizer: Spectrum Thinning at High SNRs," Information Theory, IEEE
Transactions on , vol.57, no.2, pp.953-971, Feb. 2011, 2010 The error-pattern correcting code (EPCC) is incorporated in the design of a turbo equalizer (TE) with aim to correct dominant error events of the inter-symbol interference (ISI) channel at the output of its matching Viterbi detector. By targeting the low Hamming-weight interleaved errors of the outer convolutional code, which are responsible for low ...

Fully Parallel Turbo Equalization for Wireless Communications [PDF]
IEEE Access, 2015 Iterative turbo equalization is capable of achieving impressive performance gains over the conventional non-iterative equalization having the same complexity, when communicating over channels that suffer from intersymbol interference (ISI).

Truncated Turbo Equalizer with SIC for OTFS [PDF]
arXiv, 2023 Orthogonal time frequency space (OTFS) is a promising candidate waveform for the next generation wireless communication systems. OTFS places data in the delay-Doppler (DD) domain, which simplifies channel estimation in highmobility scenarios. However, due to the 2-D convolution effect of the time-varying channel in the DD domain, equalization is still ...

Doubly-Iterative Sparsified MMSE Turbo Equalization for OTFS Modulation [PDF]
in IEEE Transactions on Communications, vol. 71, no. 3, pp.
1336-1351, March 2023, 2022 Currently, orthogonal time frequency space (OTFS) modulation has drawn much attention to reliable communications in high-mobility scenarios. This paper proposes a doubly-iterative sparsified minimum mean square error (DI-S-MMSE) turbo equalizer, which iteratively exchanges the extrinsic information between a soft-input-soft-input (SISO) MMSE estimator ...

Adaptive Turbo Equalization of Probabilistically Shaped Constellations [PDF]
arXiv, 2023 Fiber nonlinearity compensation of probabilistically shaped constellations with adaptive turbo equalization is investigated for the first time. Potential for more than 100% transmission reach extension is demonstrated by combining probabilistic shaping, single-channel digital backpropagation, and adaptive turbo equalization.

A new SISO algorithm with application to turbo equalization [PDF]
, 2005 In this paper we propose a new soft-input soft-output equalization algorithm, offering very good performance/complexity tradeoffs. It follows the structure of the BCJR algorithm, but dynamically constructs a simplified trellis during the forward ...
