MAP channel-estimation-based PIC receiver for downlink MC-CDMA systems
(Hindawi Publishing Corporation, 2008)
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 multicarrier (MC) code division multiple ...
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Anterior instrumentation for adolescent idiopathic scoliosis
(Springer Verlag, 2001)
Thirty-two patients with adolescent idiopathic scoliosis underwent anterior fusion with rigid single rod (third generation instrumentation) and titanium mesh cages. The mean follow-up was 31 (24-45) months and the mean age ...
One-stage surgical correction of congenital thoracic lordosis - report of 2 cases
(Taylor & Francis, 2001)

The evaluation of microbial contamination in platelet concentrates prepared by two different methods
(Pergamon-Elsevier Science Ltd, 2001)
The microbial contamination of platelet concentrates (PCs) prepared by two different methods both with a high risk of bacterial contamination during preparation and storage were evaluated. For apheresis platelets the ...
Going against the national cultural grain: a longitudinal case study of organizational culture change in Turkish higher education
(Carfax Publishing, 2000)
This paper presents results of a longitudinal case study inquiry into the measurement of organizational culture change through the implementation of total quality management (TQM) concepts in a higher education context. ...
Ondansetron hydrochloride for the treatment of delirium after coronary artery surgery

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 ...
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)
Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ...
Recurrent tuberculous pseudoaneurysm of the descending thoracic aorta - A case report
(WESTMINSTER PUBL INC, 2006)
Tuberculous pseudoaneurysm of the aorta is a rare disease that is uniformly fatal if not treated properly. The authors present a case of a recurrent tuberculous false aneurysm of the descending thoracic aorta that was ...
