Performance of rake-MMSE-equalizer for UWB communications

IEEE Wireless Communications and Networking Conference, 2005, 2005
The performance of a joint Rake and minimum mean square error (MMSE) equalizer receiver for high data rate ultra-wideband communications is studied in this paper. The proposed receiver combats intersymbol interference by taking advantage of the Rake and equalizer structure.

Direct semi-blind MMSE equalization for STBC

IEEE Signal Processing Letters, 2005
A semi-blind method for minimum mean square square error (MMSE) equalization of space-time block coding (STBC) systems is proposed. By exploiting information from the redundancy in the structure of STBC as well as from the training symbols, MMSE equalization can be achieved without channel estimation.

MMSE Equalization for Bandwidth-Efficient Multicarrier Systems

2006 IEEE International Symposium on Circuits and Systems, 2006
Multicarrier systems, used in many of today's communications standards like 802.11b, are very prominent candidates for future mobile communication systems. Complex modulated transmultiplexer filter banks (Tzannes et al., 1994) providing improved frequency responses in comparison to orthogonal frequency division multiplex (OFDM) are proposed without a ...

MMSE Turbo Equalizer for Channels with Cochannel Interference

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
The MMSE turbo equalizer has excellent performance with moderate complexity. Current realizations of an MMSE turbo equalizer usually assume the equalizer output is Gaussian, which, however, may not be true for channels with co-channel interference (CCI).

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 ...

Turbo Diversity Based on SC/MMSE Equalization

IEEE Transactions on Vehicular Technology, 2005
In this paper, an iterative (turbo) technique, soft-cancellation followed by minimum mean squared error filtering (SC/MMSE), is applied to the diversity combining of broadband single-carrier signals using multiple antennas. The major aim of this approach is to reduce the computational complexity of the original SC/MMSE equalization algorithm.

Chip-level MMSE equalization at the edge of the cell

2000 IEEE Wireless Communications and Networking Conference. Conference Record (Cat. No.00TH8540), 2002
We examine the performance of two linear equalizers for a CDMA downlink over a frequency-selective multipath channel: the traditional RAKE receiver, and a chip-level MMSE (minimum mean square error) equalizer. The mobile-station assumed to be midway between two base-stations.

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
