Bandwidth Efficient OFDM Transmitter Diversity Techniques
EURASIP Journal on Advances in Signal Processing, 2004 Space-time block-coded orthogonal frequency division multiplexing (OFDM) transmitter diversity techniques have been shown to be efficient means of achieving near-optimal diversity gain in frequency-selective fading channels.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Genetic diversity of Plasmodium falciparum among school-aged children from the Man region, western Côte d'Ivoire [PDF]
, 2013 The genetic diversity of Plasmodium falciparum allows the molecular discrimination of otherwise microscopically identical parasites and the identification of individual clones in multiple infections. The study reported here investigated the P. falciparum

Transmit Waveform Optimization for Spatial-Frequency Diversity MIMO Radar in the Presence of Clutter
International Journal of Antennas and Propagation, 2014 Benefitting from the independent target echoes of diversity channels, diversity MIMO radar can efficiently improve system performance, such as target detection and parameter estimation. Due to the fact that the RCS (radar cross section) of complex target

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A rate-one full-diversity low-complexity space-time-frequency block code (STFBC) for 4-Tx MIMO-OFDM [PDF]
, 2005 It is known that by employing space-time-frequency codes (STFCs) to frequency selective MIMO-OFDM systems, all the three diversity viz spatial, temporal and multipath can be exploited.

Error rate prediction for high data rate short range systems [PDF]
, 1992 Present mobile radio services offer primarily voice communication to customers roaming within large cell topographies. Typically these systems do not require large bandwidths and offer little or nothing in the way of data based services with the result ...

ESDF: Ensemble Selection using Diversity and Frequency
CoRR, 2015 Recently ensemble selection for consensus clustering has emerged as a research problem in Machine Intelligence. Normally consensus clustering algorithms take into account the entire ensemble of clustering, where there is a tendency of generating a very large size ensemble before computing its consensus. One can avoid considering the entire ensemble and

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Fast and Multicarriar Frequency Hopping Signals overFrequency Selective Rayleigh Fading Channel
Journal of Engineering and Sustainable Development, 2006 In this paper, the performance of frequency hopping spread spectrum systems employing noncoherent reception and transmission diversity is analyzed for frequency selective Rayleigh fading (FSRF) channel. Two different types of frequency diversity systems,
