Feedback reliability calculation for an iterative block decision feedback equalier [PDF]
, 2009 A new class of iterative block decision feedback equalizer (IB-DFE) was pioneered by Chan and Benvenuto. Unlike the conventional DFE, the IB-DFE is optimized according to the reliability of the feedback (FB) symbols.

SC-FDE Based MIMO Uplink Transmission Over Infrared Communication Channels
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018 In this paper, we propose a multiple-input multiple-output (MIMO) uplink transmission scheme for optical wireless communication applications. The transmission is based on optical single-carrier frequency domain equalization (SC-FDE) due to its low complexity where the signal is transmitted over infrared communication channels.
