Turbo Equalization for Underwater Communication Systems using Rotated Constellations
Oceans, 2023 The available bandwidth of the underwater acoustic channel is severely limited. Therefore, it is of interest to use modulations with high spectral efficiency, such as rotated constellations.

Spatial Coupling In Turbo Equalization
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020 In this paper we consider spatial coupling in turbo equalization and demonstrate that the code design trade-off between the performance in waterfall and error floor regions can be avoided. We introduce three coupling schemes and compare their performances, where the first method introduces coupling between the encoder and the channel, while the second ...

Fully Parallel Turbo Equalization for Wireless Communications
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).

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).
