Turbo-ICL: In-Context Learning-Based Turbo Equalization
CoRRThis paper introduces a novel in-context learning (ICL) framework, inspired by large language models (LLMs), for soft-input soft-output channel equalization in coded multiple-input multiple-output (MIMO) systems.

Parallel equalization schemes for Turbo equalizer
Tongxin xuebao, 2006 In order to reduce the equalization delay induced by iteration, two parallel methods were proposed respectively based on maximum a-posteriori probability （MAP） and linear minimum mean-squared error （LMMSE） equalization algo-rithm in Turbo equalization ...

Time-Frequency Domain Turbo Equalization for Single-Carrier Underwater Acoustic Communications
IEEE Access, 2019 Single-carrier frequency-domain equalization (SC-FDE) is a promising technique for coherent high-rate underwater acoustic (UWA) communications. In this paper, a time-frequency domain turbo equalization (TFD-TE) scheme is proposed for single-carrier ...

In vivo simultaneous proton resonance frequency shift thermometry and single reference variable flip angle T1 measurements. [PDF]
Magn Reson MedAbstract Purpose The single reference variable flip angle sequence with a multi‐echo stack of stars acquisition (SR‐VFA‐SoS) simultaneously measures temperature change using proton resonance frequency (PRF) shift and T1‐based thermometry methods. This work evaluates SR‐VFA‐SoS thermometry in MR‐guided focused ultrasound in an in vivo rabbit model ...

Sliding-Window Turbo Equalization and Its Reduced-Complexity Decoding Techniques
IEEE Access, 2022 Turbo equalization is a cooperative error-correcting approach to achieve a target bit-error rate over inter-symbol interference channels. In this paper, we proposed a new turbo equalization, called sliding-window turbo equalization (SW-TE), consisting of

Doubly-Iterative Sparsified MMSE Turbo Equalization for OTFS Modulation [PDF]
IEEE Transactions on Communications, 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 ...

Adaptive Turbo Equalization for Nonlinearity Compensation in WDM Systems [PDF]
Journal of Lightwave Technology, 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 ...

Turbo Equalization With Irregular Turbo Codes [PDF]
2007 4th International Symposium on Wireless Communication Systems, 2007 We analyze a turbo equalization system that combines maximum a posteriori probability (MAP) equalization with irregular turbo codes. Our goal is to approach the information capacity limit for severe inter-symbol interference (ISI) channels. To this end, we optimize the degree profile of irregular turbo codes by maximizing the minimum distance between ...

A Sliding-Window LMMSE Turbo Equalization Scheme for OTFS
IEEE Communications Letters, 2023 This letter discusses a recently proposed linear minimum mean square error (LMMSE) turbo equalization scheme for OTFS. The complexity of the LMMSE-based equalizer, measured by the number of complex multiply-and-addition operations, scales with the cube ...
