摘要： Provided are a 3-port orthogonal mode transducer, and a receiver and receiving method using the same. The 3-port orthogonal mode transducer includes: a transmission port having a rectangular shape elongated in a horizontal direction and configured to transmit a Ka-band (30 GHz) vertical polarization signal; a first reception port having a rectangular shape inclined at about +45 degrees at a location being at about +45 degrees with respect to the transmission port and configured to receive a K-band (20 GHz) vertical or horizontal polarization signal phased-delayed about +45 degrees; and a second reception port having a rectangular shape inclined at about −45 degrees at a location being at about −45 degrees with respect to the transmission port and configured to receive a K-band (20 GHz) vertical or horizontal polarization signal phase-delayed about −45 degrees.

摘要： Provided are an adaptive coding modulation (ACM)-based simulcast transmission and reception apparatus and method. The apparatus includes a transmitter configured to analyze whether or not it is raining in a region where a receiver is present on the basis of channel state information (CSI) provided by the receiver, encode and/or modulate an image signal according to the analysis result, and provide the encoded and/or modulated image signal through a single band or multiple bands. On the basis of a result of analyzing whether or not it is raining in a region where a receiver is present, it is possible to effectively prevent signal attenuation caused by rain by providing image signals having different resolutions through multiple bands when the region is in a rainfall state.

摘要： A center district network synchronization acquisition apparatus and method capable of accommodating both a GPS mode based terminal and an NCR mode based terminal. The center district network synchronization acquisition apparatus for a satellite communication system according to an exemplary embodiment includes: a timing generating unit configured to generate an interrupt signal by being synchronized with a PPS (pulse per second) signal received from a reference clock generation module, an NCR counter configured to extract a corresponding NCR (network clock reference) value at a timing indicated by the interrupt signal, and a packet generating unit configured to generate an MPEG2-TS packet including the NCR value extracted according to the interrupt signal. Therefore, this apparatus can accommodate both a GPS mode based terminal and an NCR mode based terminal. As a result, the satellite communication system can operate regardless of the network synchronization mode performed by the terminal.
