Blind MMSE equalization: a new direct method

2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002
We propose a blind MMSE equalization algorithm to compute fractionally spaced blind equalizers with arbitrary delay directly from second order statistics of the observations. The algorithm is based on multi-channel linear prediction. Performance analysis demonstrates that our algorithm has higher signal-to-interference-plus-noise-ratio (SINR) than its ...

An Extending Window MMSE Turbo Equalization Algorithm

IEEE Signal Processing Letters, 2004
We present a modified turbo minimum mean-squared error (MMSE) equalization algorithm using an extending window approach. We show that the new method can achieve nearly the same performance and considerable cost reduction compared with a recently proposed sliding window MMSE equalization technique.

Adaptive Cholesky based MMSE equalizer in GSM

APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008
The most wireless communication systems uses the equalization in order to remove the inter-symbol interference (ISI) due to the multipath fading channel impairment. When the minimum mean square error (MMSE) equalizer is applied, the linear system solution requires very high computational complexity so that the equalization would be the most critical ...

Suboptimal Linear MMSE Equalizers With Minimum Redundancy

IEEE Signal Processing Letters, 2010
Recent works have proposed practical zero-forcing (ZF) and linear minimum mean squared-error (LMMSE) solutions for fixed and memoryless block-based transceivers with minimum redundancy, using only half the amount of redundancy employed in standard systems. Their equalization processes require only O(M log2 M) operations. However, it may be difficult to

An adaptive algorithm for blind MMSE equalization of SIMO channels

Journal of Ambient Intelligence and Humanized Computing, 2013
In this work, an adaptive method for estimating blind MMSE equalizer with arbitrary delay of SIMO channel is proposed. By using an RLS-similar algorithm to recursively update correlation matrix and its pseudo inverse, the proposed algorithm ensures convergence and is not sensitive to initialization.

MMSE WL Equalizer in Presence of Receiver IQ Imbalance

IEEE Transactions on Signal Processing, 2008
In this correspondence, with reference to the transmission over a linear time-dispersive channel, we address the problem of the in-phase and quadrature-phase (IQ) imbalance compensation when a single-carrier modulation scheme is used. Low-cost fabrication technologies and high data-rate transmissions render the conventional receivers very sensitive to ...

Elimination of DC Offset by MMSE Adaptive Equalizers

IEEE Transactions on Communications, 1976
Data communication systems are often beset with the problem of dc offset. The questions addressed and answered in this concise paper are: 1) can minimum mean-squared error (MMSE) equalizers correct dc offset? 2) what are the exact effects of the equalizer on offset, and offset on residual MSE?

A Modified DFE-MMSE Equalization Algorithm

Advanced Materials Research, 2014
In wireless communication, inter symbol interference (ISI) and signal distortion are often caused by the frequency deviation and time offset of wireless channel. To eliminate or reduce ISI, people proposed the channel equalization technology. However, traditional decision feedback equalization algorithm based on MMSE criterion equalizer (DFE-MMSE ...

MMSE Equalization of Interference on Fading Diversity Channels

IEEE Transactions on Communications, 1984
Adaptive equalization is used in digital transmission systems with parallel fading channels. The equalization combines the diversity channels and reduces intersymbol interference due to multipath returns. When interference is present and correlated from channel to channel, the equalizer can also reduce its effect on the quality of information transfer,

MMSE non uniformly spaced equalizers

Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005
Non uniformly spaced equalizers (NUSE) were recently proposed as an alternative to fractional spaced equalizers (FSE) and baud spaced equalizers (BSE). A key result pertaining to this new class of equalizers is that, under certain channel conditions, NUSE FIR zero forcing solutions operating at the lower BSE rate exist.
