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 for Nonlinearity Compensation in WDM Systems [PDF]
arXiv, 2021 In this paper, the performance of adaptive turbo equalization for nonlinearity compensation (NLC) is investigated. A turbo equalization scheme is proposed where a recursive least-squares (RLS) algorithm is used as an adaptive channel estimator to track the time-varying intersymbol interference (ISI) coefficients associated with inter-channel nonlinear ...

Performance of Blind Turbo Equalizer in Indoor Channels [PDF]
Journal of Communications Software and Systems, 2011 In this paper, we consider the transmission of turbo coded symbols in the indoor radio environment. The system isaffected by the intersymbol interference (ISI) caused by the multipath time-delay spread of the transmission medium.

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 ...

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 ...
