Pilot Symbol Aided Channel Estimation for Spatial Modulation-OFDM Systems and its Performance Analysis with Different Types of Interpolations
(Springer, 2017)
Spatial modulation orthogonal frequency division multiplexing (SM-OFDM) system has been recently proposed as an alternative for multiple-input multiple-output (MIMO)-OFDM systems to increase spectral efficiency by keeping ...
A Mobile Channel Model for VLC and Application to Adaptive System Design
(IEEE-INST Electrical Electronics Engineers Inc, 2017)
In this letter we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing we first obtain channel impulse responses for each point over the user ...
Which anesthetic agent alters the hemodynamic status during pediatric catheterization? Comparison of propofol versus ketamine
(W.B. Saunders Co Ltd, 2003)
Objective: To compare the effects of propofol and ketamine on systemic and pulmonary circulations in pediatric patients scheduled for elective cardiac catheterization. Design: Prospective randomized and blinded. Setting: ...
Corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism of the keratoconus. Follow-up after 2 years
(Masson Editeur, 2003)
Objective: To evaluate the use of corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism in keratoconus. Material and methods: This prospective study involved nine eyes of seven patients who were ...
Unconditional maximum likelihood approach for localization of near-field sources in 3-D space
(IEEE, 2004)
Since maximum likelihood (ML) approaches have better resolution performance than the conventional localization methods in the presence of less number and highly correlated source signal samples and low signal to noise ...
Cognitive impairment in amyotrophic lateral sclerosis: evidence from neuropsychological investigation and event-related potentials
(Elsevier Science Bv, 2002)
The presence of subclinical cognitive impairment in patients with amyotrophic lateral sclerosis (ALS) is investigated using neuropsychological assessment and event-related potential recordings (ERP). An extensive battery ...
Surgical treatment of tachyarrhythmias due to postinfarction left ventricular aneurysm with endoaneurysmorrhaphy and cryoablation
(Elsevier Science Bv, 2002)
Objective: In this study the efficacy of left ventricular (LV) endoaneurysmorrhaphy and cryoablation without intraoperative electrophysiologic mapping was evaluated in patients with postinfarction LV aneurysm and sustained ...
The role of oxygen saturation measurement and body mass index in distinguishing between non-apnoeic snorers and patients with obstructive sleep apnoea syndrome
(Blackwell Publishing Ltd, 2002)
The aim of this study was to examine the role of oxygen saturation (SaO(2)) measurement in identifying apnoeic snorers from non-apnoeic snorers and in the assessment of the severity of obstructive sleep apnoea. Ninety-two ...
Monostotic fibrous dysplasia of the clivus: MRI and CT findings
(Springer Verlag, 2002)
Fibrous dysplasia is a developmental disorder caused by abnormal proliferation and maturation of fibroblasts resulting in replacement of mature bone by structurally weak immature woven bone. Clival involvement in monostotic ...
