Deterministic Blind Subspace MIMO Equalization [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A subspace based approach for the blind multiple signal separation and recovery for MIMO systems is proposed in this paper. Instead of using the statistics of the received signal, the proposed algorithm exploits the received signal structure and the ...

The blind decision feedback equalizer with the entropic: Leaky decorrelation algorithm [PDF]

open access: yesTehnika, 2015
This paper presents the blind decision feedback equalizer (DFE) which transforms its soft feedback filter (SFBF) from the linear décor relator of received signal to the nonlinear soft feedback equalizer, and vice reversa, in order to eliminate the error ...

Blind paraunitary equalization [PDF]

open access: yesSignal Processing, 2009
In this paper a blind MIMO space-time equalizer is described, dedicated to convolutive mixtures when observations have been pre-whitened. Filters preserving space-time whiteness are paraunitary; a parameterization of such filters is proposed. Theoretical developments then lead to a numerical algorithm that sweeps all pairs of delayed outputs.

A Gaussian Mixture Approach to Blind Equalization of Block-Oriented Wireless Communications

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
We consider blind equalization for block transmissions over the frequency selective Rayleigh fading channel. In the absence of pilot symbols, the receiver must be able to perform joint equalization and blind channel identification.

OF-FSE: An Efficient Adaptive Equalization for QAM-Based UAV Modulation Systems

open access: yesDrones, 2023
Quadrature amplitude modulation (QAM) is one of the essential components of unmanned 1 aerial vehicle (UAV) communications. However, the output signal accuracy of QAM deteriorates dramatically and even collapses in the case of UAVs in a harsh channel ...
