Abstract: The present disclosure provides an ultrasound imaging apparatus. The ultrasound imaging apparatus includes an ultrasonic probe for transmitting an ultrasound signal toward an object, receiving an echo ultrasound signal reflected from the object, and transforming the echo ultrasound signal to an electric signal; a beamformer for beamforming and outputting the electric signal; an image reconstruction unit for generating a reconstructed image by applying a Point Spread Function (PSF) to an ultrasonic image corresponding to the output signal; and an image post-processor for performing filtering to emphasize a peak point of the reconstructed image. The use of a filter to emphasize a peak point may facilitate an accurate setting of a phase parameter to be used in estimation of a PSF. Accordingly, an almost ideal PSF may be estimated, image reconstruction is performed using the estimated PSF, and thus a high resolution image may be obtained.

Abstract: A method of adaptive channel quality calculation by a User Equipment in a mobile communication system is provided. The method includes calculating a filtering coefficient indicating a length of a filtering interval according to a Carrier to Interference-plus-Noise Ratio (CINR) variation rate of each subband per unit time, and calculating a channel quality of each subband filtered according to the filtering coefficient. An environment having a large scheduling gain according to the difference in the channel quality of each subband and an environment not having as large a scheduling gain are thereby discriminated from each other in measurement of the channel quality of each subband, to apply different Infinite Impulse Response (IIR) filtering coefficient values a used for calculation of CINR of each subband.
