Blind adaptive decision feedback equalization: A class of channels ...
Mar 1, 1998 · In this paper, we propose beamforming schemes for frequency-selective channels with decision-feedback equalization (DFE) at the receiver and with, respectively, perfect and …
Channel equalization for very high-speed digital data …
A simulation study of an adaptive FSE/DFE receiver demonstrates that the 6 dB of NEXT noise margin is achievable with a 21-tap half baud-spaced FSE and a 60-tap DFE on a 9-kft 26 …
An efficient FSE/DFE-based HDSL equalizer with new adaptive …
We consider the design of an efficient FSE/DFE-based HDSL equalizer. For this, several variants of the conventional LMS algorithm and their delayed versions are investigated. In addition, two …
Blind decision feedback equalisers, how to avoid degenerative …
Nov 1, 2002 · Convergence to degenerative solutions characteristic of the algorithm DFE_CMA and DFE_CMA_FF is avoided if the algorithm DFE_CMA_FB is used (cf. Fig. 6). The new …
The structure of Soft-DFE: (a) linear T/2 fractionally ... - ResearchGate
In blind acquisition mode, the Soft-DFE is the linear equalizer consisting of: (i) the SFBF-FSE cascade where the SFBF is a pure recursive whitener that compensates, in predictive manner, …
