Blind Turbo equalization algorithm based on hidden Markov model for continuous phase modulation signals

Tongxin xuebao, 2015
To solve the issues of the poor performance and convergence difficulties in the blind equalization of high order continuous phase modulation (CPM) signals, a new EM-SOVA channel blind equalization method was developed from the perspective of hidden ...

Variable observation window length blind equalization detector for underwater acoustic communication

EURASIP Journal on Wireless Communications and Networking, 2020
Aiming at the influence of underwater acoustic channel (UAC) profile difference on the performance of underwater acoustic communication, a variable observation window length blind equalization detector (VOWL-BED) is proposed in this paper.

Managing the meniscus part I—Anatomy, biomechanics, and treatment strategies for the atraumatic meniscus tear

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this article is to serve as the first of a two‐part review on the meniscus; in this review, we will establish the background on anatomy and pathogenesis of the meniscus, as well as the effect of the meniscus on native knee kinematics and function.

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Extensive Subcutaneous Emphysema and Pneumomediastinum Following Eustachian Tube Dilation and PET Insertion: A Rare Complication

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Eustachian tube dilation (ETD) is an increasingly popular and seemingly safe method of treating ETD. We present a rare case of subcutaneous emphysema and pneumomediastinum following ETD. Methods Retrospective chart review. Patient consent was obtained for data collection, analysis, drafting, and publication of information ...

Blind Equalization Using Direct Channel Estimation [PDF]

, 2004
In performing blind equalization, we propose a direct channel estimation method based on entropy-maximization of input signal with its known probability density function. That is, the proposed method estimates filter coefficients of the channel instead of equalizing filter coefficients which most of equalization methods try to estimate.

The Impact of Vertical Fiscal Imbalance on Gambling Policies in New South Wales, Australia: The Rise of the Poker Machine

Australian Journal of Politics &History, EarlyView.
ABSTRACT This study traces how gambling in Australia changed from a simple form of leisure, enjoyed by all social classes in colonial times, to a billion‐dollar industry driven by political and economic imperatives. Using a case study, it links vertical fiscal imbalance (VFI), caused by changes to the state‐federal taxation structure, to the ...

Cannabinoid CB1 allosteric ligands suppress inflammatory pain in male mice without tolerance, motor impairment, memory deficits or respiratory depression

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Positive allosteric modulators (PAMs) engage sites distinct from the orthosteric CB1 cannabinoid receptor binding site. GAT211, a racemic ligand, contains GAT228 (R) and GAT229 (S) enantiomers. Whether enantiomer‐mediated differences in allosteric activation or positive allosteric modulation translate into differences in
