Intravertebral vacuum phenomenon that developed during transpedicular biopsy
(W.B. Saunders Co Ltd, 2002)
[Abstract Not Available]
Intraoperative saline-irrigated radiofrequency modified maze procedure for atrial fibrillation
(Elsevier Science Inc, 2002)
Background. This study was conducted to evaluate the effectiveness of the saline-irrigated radiofrequency modified Maze operation for treatment of chronic atrial fibrillation and to compare the results of the left and ...
Ondansetron hydrochloride for the treatment of delirium after coronary artery surgery
(Mosby Inc, 2001)
[Abstract Not Available]
Does off-pump coronary artery bypass surgery reduce mortality in high risk patients?
(Forum Multimedia Publishing LLC., 2001)
Background: The aim of this retrospective study was to compare outcome in two groups of patients who were classified according to their risk groups and underwent coronary revascularization with or without cardiopulmonary ...
Space-time coded systems with joint transmit and receive antenna selection
(IEEE, 2007)
This paper studies performance of space-time coded (STC) systems with joint transmit and receive antenna selection over multiple input multiple output (MIMO) flat and frequency-selective (FS) fading channels. Specifically ...
Distributed estimation with channel estimation error over orthogonal fading channels
(IEEE, 2007)
We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ...
Channel estimation for MIMO-OFDM systems in fixed broadband wireless applications
(IEEE, 2007)
Systems employing multiple transmit and receive antennas known as multiple input multiple output (MIMO) systems can be used with OFDM to improve the resistance to channel impairments. Thus the technologies of OFDM and MIMO ...
EM-Based MAP channel estimation and data detection for downlink MCC-CDMA systems
(IEEE, 2007)
In this work we propose a joint MAP channel estimation and data detection technique based on the Expectation Maximization (EM) method with paralel interference cancelation(PIC) for downlink multi-carrier (MC) code division ...
EM-based joint data detection and channel estimation for uplink MC-CDMA systems over frequency selective channels
(IEEE, 2007)
This paper is concerned with joint channel estimation and data detection for uplink multicarrier code-division multiple-access (MC-CDMA) systems in the presence of frequency fading channel. The detection and estimation ...
Blind-phase noise estimation in OFDM systems by sequential Monte Carlo method
(John Wiley and Sons Ltd, 2006)
One of the main drawbacks of orthogonal frequency division multiplexing (OFDM) systems is the phase noise (PN) caused by the oscillator instabilities. Unfortunately due to the PN the most valuable feature namely orthogonality ...
