20100046421Multibeam Antenna System - Embodiments of the invention relate to beamforming antennas such as can be used in space division multiplexing systems. Space division multiplexing can be used to increase data capacity in wireless networks by enabling different base stations to transmit signals within the same frequency band. Each antenna beam can potentially be used to establish a communication link within an area of wireless coverage, and other communication links established on other antenna beams then represent interference to that user. In order to reduce interference, narrow beamwidths are desirable. These are typically achieved by increasing the aperture of the antenna in the azimuth plane, and in arrangements that require finely divided angular sectors, a greater number of antennas will be required to give three hundred and sixty degree coverage. As a result, there is potentially a large increase in the total surface area of antennas which is undesirable, as it leads to increased wind loading of an antenna tower. Embodiments of the invention provide an arrangement in which data are transmitted from a first transmitter to a first receiver using a first antenna beam, and data are transmitted from a second transmitter to a second receiver using a second antenna beam. The first antenna beam is formed by splitting the signal from the first transmitter into two parts with a first phase relationship between the parts, each part being connected to an antenna. A second antenna beam is formed by splitting the signal from the second transmitter into two parts with a second phase relationship between the parts, each part being connected to one of the two antennas. An advantage of embodiments of the invention is that data can be transmitted from different transmitters at the same frequency without interference, while presenting a smaller antenna aperture than is required with conventional systems.02-25-2010

20090290532MAP-TRIGGERED DUMP OF PACKETS IN SATELLITE COMMUNICATION SYSTEM - Upstream information arriving through a user terminal in a satellite link is efficiently scheduled through a modified Demand Assigned Multiple Access (DAMA) algorithm such that data packets arriving at the user terminal are concatenated to form a larger frame for transmission and the concatenated packet is held in a first queue disposed ahead of a second queue, where the data in the second queue cannot be modified (typically a hardware queue), sufficient to allow the second queue to be emptied.

20100315993BROADCAST SYSTEM AND ITS METHOD - A sorting section in a restoration section sorts out a packet for an intended service from a transport stream received according to the control of a reception control section. The sorted out packet is provided to an output section and restored to NTSC signals. An audiovisual output section (such as a TV set) receives the signals and outputs images and voices. The reception control section acquires information on the type of contents chosen out of the transport stream through the sorting section, and further compares the contents type information with restorable contents type information recorded in a restorable contents type information recording section. Then, a determination is made whether or not the contents intended for restoration are restorable. Depending on the determination, the manner of process applied to the contents is changed. For example, the restoration of the contents is interrupted.12-16-2010
