Provided is an image interpolation method and apparatus using a reference block depending on a direction. The image interpolation method may generate a horizontal reference block and a vertical reference block each with respect to an inputted image, and determine interpolation directivity with respect to the inputted image using the generated horizontal reference block and vertical reference block, thereby performing an interpolation on an image based on accurate interpolation directivity. In particular, the image interpolation method may determine whether to verify interpolation directivity depending on an edge intensity of an inputted image, thereby performing a color filter array (CFA) interpolation on an image based on an edge direction without determining the interpolation directivity, when the edge intensity is strong.

The present invention separates inputted triple play IP data into Internet and TV data and voice (VoIP) data, encodes the Internet and TV data permitting a long delay time according to the existing DVB-S2 standard, and encodes the voice data permitting only a short delay time according to a DVB-RCS+M standard based 4K mode. Each encoded data is subjected to the orthogonal modulation and the orthogonally modulated voice data is subjected to a direct sequence spectrum spread according to a spreading factor. The spread spectrum signal is multiplexed in a SCPC frequency division multiple access (FDMA) scheme so as to overlap with frequencies allocated to each user.

Provided are a non geostationary satellite orbit (NGSO) communication apparatus that extends an operation time using an ancillary territory component (ATC) and reduces a number of satellites, and an ATC and an operating method thereof. The NGSO communication apparatus extends an operation time using an ATC and reduces a number of satellites from a first ATC that communicates with a mobile earth station (MES), and a second ATC that communicates with the first ATC to relay data between the MES and the satellite when the first ATC is unable to communication with the satellite revolving along an orbit.

The present invention relates to a system and method of reusing radio resources capable of improving radio resource efficiency. According to an embodiment of the present invention, in a communication system including a repeater that retransmits signals transmitted from a satellite to user terminals, it is possible to reuse some of the radio resources used in a wide area coverage, such as the satellite, in a repeater coverage. Therefore, it is possible to ensure radio resources such that repeater data can be transmitted to user terminals without additional radio resources.

A microelectronic structure includes a conductive pad on a substrate. The conductive pad includes first and second openings extending therethrough. A first conductive via on the conductive pad extends through the first opening in the conductive pad into the substrate. A second conductive via on the conductive pad adjacent the first conductive via extends through the second opening in the conductive pad into the substrate. At least one of the conductive vias may be electrically isolated from the conductive pad. Related devices and fabrication methods are also discussed.

A method for optimizing phase factors in partial transmit sequence orthogonal frequency division multiplexing system. The method includes initializing sub-block signals by applying an initial phase factor to the sub-block signals in all sub-blocks; setting a reference peak value with a peak value of a signal formed by combining the sub-block signals; selecting a phase value that minimizes the peak value of an output signal as the phase factor of each sub-block by applying a next phase value to each sub-block signal as the phase factor, and repeating this with respect to the remaining available phase values.
