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 ...
A computational study on the amine-oxidation mechanism of monoamine oxidase: Insight into the polar nucleophilic mechanism
(Royal Soc Chemistry, 2006)
The proposed polar nucleophilic mechanism of MAO was investigated using quantum chemical calculations employing the semi-empirical PM3 method. In order to mimic the reaction at the enzyme's active site the reactions between ...
