Title: Phase correction for ofdm and mimo transmissions
Inventor: WALTON J RODNEY
IPC: H04B1/12
Filed: 2007-05-22
Abstract: Techniques for performing phase correction for wireless communication are described. Received pilot symbols and received data symbols may be obtained from an orthogonal frequency division multiplexing (OFDM) and/or multiple-input multiple-output (MIMO) transmission. First phase information is obtained based upon the received pilot symbols. Second phase information is obtained based upon the received data symbols. The phase of the received data symbols is corrected based upon the first and second phase information (directly and/or indirectly). For example, the phase of the received data symbols may be corrected based upon the first phase information, detection may be performed on the phase corrected data symbols to obtain estimated data symbols, the second phase information may be obtained based upon the estimated data symbols, and the phase of the estimated data symbols may be corrected based upon the second phase information. The phase correction may also be performed in other manners.

Abstract: This invention relates generally to non-destructive testing and in particular to ultrasound imaging. A adaptive beamforming imaging method of operating a portable ultrasound imaging system having an array of transducer elements is disclosed. The method comprises transmitting a plurality of beamforming ultrasound signals with each transmission using a different sub-aperture of the array; receiving a reflected ultrasound signals and producing DAS (Delay and Sum) beamforming under each individual sub-aperture transmission. Meanwhile, a coherency factor was calculated based on the proportion of coherent energy in the received time delayed signals from each sub-aperture transmission. All beamforming imaging under defined sub-aperture transmissions were adaptive coherent weighted and synthetised into the final beamforming output. The presented method enables a portable imaging system generating imaging with good quality clarity, contrast and resolution; but less complex hardware and low calculating requirements.

Abstract: Des systèmes et des méthodes sont présentés pour comprimer un fluide cryogénique à l'aide d'un compresseur multiétage. Un fluide réfrigérant dans une première boucle de refroidissement refroidit des chemises de refroidissement des étages de compression et/ou des échangeurs de chaleur intermédiaires et réchauffe un échangeur de chaleur de précompression. La température du fluide réfrigérant dans le premier échangeur de chaleur est modérée par l'échange de chaleur d'air ambiant. Le fluide de traitement est refroidi de manière élective par un des échangeurs de chaleur intermédiaires après chaque étage de compression si la température du fluide de traitement est supérieure au critère de température. Le système peut ainsi fonctionner pendant une période transitoire (période de refroidissement progressif) sans fluide de traitement de ventilation. Les échangeurs de chaleur intermédiaires sont préférablement contournés lorsque le système atteint la température de fonctionnement à l'état stable.
