Turbo Equalization Of Nonlinear ISI-channels Using High Rate FEC Codes [PDF]

Advances in Radio Science, 2005
Turbo equalization is a widely known method to cope with low signal to noise ratio (SNR) channels corrupted by linear intersymbol interference (ISI) (Berrou and Galvieux, 1993; Hagenauer et al., 1997).

Iterative Estimation in Turbo Equalization Process [PDF]

Journal of Electrical and Electronics Engineering, 2014
This paper presents the iterative estimation in turbo equalization process. Turbo equalization is the process of reception in which equalization and decoding are done together, not as separate processes.

Combined Serially Concatenated Codes and MMSE Equalization: an EXIT Chart Aided Perspective

, 2006
Iterative Minimum Mean Square Error (MMSE) equalization and channel decoding is appealing, since it exhibits a lower complexity than maximum a posteriori (MAP) turbo equalization.

Tissue‐specific recombination‐activated clonal and inducible transcription (TRAC‐IT) enables controlled gene activation in stably marked tissues

The Plant Journal, Volume 127, Issue 6, September 2026.
Significance Statement Tissue‐specific Recombination‐Activated Clonal and Inducible Transcription (TRAC‐IT), a two‐step system that uncouples inducible gene expression from cell identity. TRAC‐IT offers a versatile tool that provides new technical possibilities to explore the mechanisms driving plant development in a stable tissue‐specific fashion.

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

Radio Science, Volume 61, Issue 8, August 2026.
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

Blind Turbo equalization algorithm based on hidden Markov model for continuous phase modulation signals

Tongxin xuebao, 2015
To solve the issues of the poor performance and convergence difficulties in the blind equalization of high order continuous phase modulation (CPM) signals, a new EM-SOVA channel blind equalization method was developed from the perspective of hidden ...
