An adaptive algorithm for blind MMSE equalization of SIMO channels
Journal of Ambient Intelligence and Humanized Computing, 2013In 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.

Elimination of DC Offset by MMSE Adaptive Equalizers
IEEE Transactions on Communications, 1976Data 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, 2014In 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 WL Equalizer in Presence of Receiver IQ Imbalance
IEEE Transactions on Signal Processing, 2008In 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 ...

MMSE Equalization of Interference on Fading Diversity Channels
IEEE Transactions on Communications, 1984Adaptive 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,

Implementation of the Levinson algorithm for MMSE equalizer
2008 International SoC Design Conference, 2008In wireless communication system applying the minimum mean square error (MMSE) as its equalization algorithm, the equalizer is one of the most critical part in terms of the computational complexity of the baseband signal processing. Hence more efficient algorithm implementing MMSE equalizer is needed to save power consumption and reduce the hardware ...

On MMSE fractionally-spaced equalizer design
Proceedings of 13th International Conference on Digital Signal Processing, 2002This paper adds analytical tools to an evolving theory on fractionally-spaced equalizer (FSE) design. It examines the minimum mean square error design (MMSE-FSE) for channels perturbed by additive noise in two scenarios: when the equalizer is finite, but is at least as long as the channel, and when the equalizer has an infinite impulse response (IIR ...

MMSE non uniformly spaced equalizers
Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005Non 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.

Linear MMSE Frequency Domain Equalization with Colored Noise
2007 IEEE 66th Vehicular Technology Conference, 2007The use of oversampling at the receiver results in colored noise when the bandwidth of the noise-limiting filter is not sufficiently large. This paper proposes a fractionally-spaced single-carrier linear MMSE frequency domain equalizer (LMMSE-FDE) over frequency-selective multiple input multiple output (MIMO) channels.

A new blind adaptive MMSE equalizer for MIMO systems
2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006In this paper, we consider the problem of blind equalization of MIMO systems. In a recent work a blind MMSE equalizer robust to channel order over-estimation errors was proposed for SIMO systems. In this work, we extend this method and propose a new MMSE algorithm that presents better robustness and better tracking performances.
