Conjugate gradient based MMSE Decision Feedback Equalization
2008 IEEE International Symposium on Wireless Communication Systems, 2008The performance of linear filters degrade drastically when applied to mitigate intersymbol interference caused by channels with frequent nulls in their spectral characteristics like, e.g., time-dispersive radio channels. In such cases, the well-known decision feedback equalizer (DFE) is one possible nonlinear approach to improve the quality of the ...

A note on optimum MMSE/ZF multichannel equalization delay
2010 17th International Conference on Telecommunications, 2010The reconstruction delay has been, for long time, recognized a significant impact on the performance of an equalizer. Still, no proofs were given that sustain the experimental observations. In this note, we develop a formal analysis that shows that optimum equalization performance is met at a delay larger than the channel memory and smaller than the ...

Novel exact low complexity MMSE turbo equalization
2008 IEEE 19th International Symposium on Personal, Indoor and Mobile Radio Communications, 2008In this paper we analyze low complexity turbo equalization that combines interference canceling and soft-input soft-output (SISO) decoding. We derive a new, exact MMSE solution for the equalization part taking into account the cross-correlation between the linear equalizer output and the soft decisions in the turbo equalization feedback loop as well as

Turbo Equalization without MMSE Filtering
2005The filter-based turbo equalization scheme has been proposed in several papers to avoid the prohibitive complexity imposed by the trellis-based turbo equalization. In the existing literature,the filter-based approach has been solely implemented by a linear MMSE filter, the coeffi cients of which are updated to minimize the mean-square error for every ...
