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 ...

Optimizing of Iterative Turbo Equalizer for Underwater Sensor Communication
International Journal of Distributed Sensor Networks, 2013 We presented an iterative turbo equalization to cope with intersymbol interference induced by reflection of sea level and sea bottom for underwater sensor communication channel. Iterative turbo equalizer consists of inner codes and outer codes; we employ

Performance Analysis and Improvement for VAMP Soft Frequency-Domain Equalizers
IEEE Access, 2019 The vector approximate message passing (VAMP) soft frequency-domain equalizer (SFDE) has been proposed for turbo equalization. It consists of an inner soft equalizer (ISE) and an inner soft slicer (ISS), which iteratively exchange block-wise extrinsic ...

Low-Complexity Iterative Receiver for Space-Time Coded Signals over Frequency Selective Channels
EURASIP Journal on Advances in Signal Processing, 2002 We propose a low-complexity turbo-detector scheme for frequency selective multiple-input multiple-output channels. The detection part of the receiver is based on a List-type MAP equalizer which is a state-reduction algorithm of the MAP algorithm using ...

Robust turbo equalization under channel uncertainties
2011 IEEE Radio and Wireless Symposium, 2011 Robust turbo equalization over discrete time channels with inter-symbol interference (ISI) in the presence of channel uncertainties is investigated. The turbo equalization framework proposed in this paper contains a linear equalizer (LE) and a trellis based decoder.
