Multiple-relay aided distributed turbo coding assisted differential unitary space-time spreading for asynchronous cooperative networks [PDF]
, 2010 This paper proposes a cooperative space-time coding (STC) protocol, amalgamating the concepts of asynchronous cooperation, non-coherent detection as well as Distributed Turbo Coding (DTC), where neither symbol-level time synchronization nor CSI ...

A high‐precision timing and frequency synchronization algorithm for multi‐h CPM signals
IET CommunicationsIn the context of certain specific digital communication systems, where there are limitations such as spectral resources and energy availability, continuous phase modulation (CPM) emerges as an appealing choice among various modulation methods. Among CPM

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Aquaporin‐4 in Narcolepsy Type 1: Investigation of Perivascular Fluid Movement in Sleep Disorders
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Narcolepsy type 1 (NT1) is caused by the loss of hypocretin‐1 leading to excessive daytime sleepiness and cataplexy. Additionally, disrupted nighttime sleep has become an increasingly recognized feature of NT1. As the glymphatic fluid movement has been linked to sleep architecture, we investigated cerebrospinal fluid (CSF) Aquaporin‐4 (AQP4 ...

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Synchronization technics for OFDM systems
, 2006 [ENGLISH] The thesis deals with the problem of synchronization in Orthogonal Frequency Division Multiplexing (OFDM) systems. This modulation technique has been in existence since 1960, however, in the last years OFDM modulation is emerged as a key ...

Iterative Symbol Timing Synchronization by Interpolation on Autocorrelation Coefficients
工程科学与技术, 2017 :In a wireless digital communication system,a digital receiver was sampled with a fixed system clock.The asynchronous digital inputs may cause symbol time offset.To tackle the issue of symbol timing synchronization,this paper proposed an iterative symbol
