摘要： Methods and apparatus are described for management of traffic comprising a statistical shaper having a plurality of inputs each for receiving a data stream and a plurality of outputs forming a variable rate bit streams; a multiplexer which combines the bit streams to form an output stream; a modulation stage which is operable to use one or more of a plurality of different modulation schemes to modulate the bit streams onto an output bearer; and, a controller which is operable to control the amount of data arriving at the modulation stage. The controller performs rate control of the data arriving at the modulation stage so that the rate of data output in the output stream from the modulator stage is within a predetermined limit for the transmission channel. For example if the modulation rate for any one bitstream changes, this would alter the rate of data transmission after the modulation stage except that excess data is stored in buffers. For example, by controlling the data rate arriving at the modulator stage, the controller regulates the amount of data stored in buffers at the modulation stage.

摘要： A dual band, higher and lower frequency range transducer with a circular coaxial waveguide feed is described having a first junction for connection of a lower frequency range outer waveguide of the coaxial waveguide feed to at least two rectangular or ridge waveguides offset from the longitudinal axis of the transducer and a second junction for connection of the at least two rectangular or ridge waveguides to a further waveguide. A third junction is provided for connecting an inner waveguide of the coaxial waveguide feed to a higher frequency range waveguide. The transducer comprises at least first and second parts joined across a first plane substantially perpendicular to the longitudinal axis and including at least a portion of the higher frequency range waveguide extending within the first plane of the join. A seal such as an 'O' ring seal may be placed easily in the plane of the join thus preventing moisture ingress. Similarly, a feed horn and input and output ports may be sealingly attached to the first and second parts of the transducer. The first and second junctions are preferably impedance matched turnstile junctions.

摘要： The present invention relates to a controller device for a satellite communication system wherein one or more beam hoppers during a hopping period each illuminate a plurality of contours according to a hopping plan indicating an order in which said plurality of contours is illuminated. The controller device comprises a dynamic hopping plan calculation module for calculating said hopping plan and is arranged for conveying said calculated hopping plan to a transmitter of said satellite communication system, whereby said dynamic hopping plan calculation module is arranged to calculate said hopping plan by subdividing, per beam hopper, said hopping period in at least two scheduling frames, said at least two scheduling frames forming said calculated hopping plan, whereby each scheduling frame comprises at least n hopping slots each indicating a contour to be illuminated, with n an integer equal to the number of contours illuminated by said beam hopper and a hopping slot denoting the minimum illumination time duration and whereby each contour of said number of contours is illuminated at least once per scheduling frame.

摘要： A wireless multiple access communication system (5) comprises a forward link (31) to a terminal (40) and a return link (32) from a terminal (40). The return link (32) uses a medium which is shared between terminals (40) on the basis of time and frequency. A terminal (40) transmits a return link signal (32) from the terminal comprising a sequence of transmission slots (51, 52, 53), each transmission slot being defined as a time slot and, carrier frequency, wherein carrier frequency and symbol rate can change between transmission slots. The return link signal (32) is transmitted continuously across the sequence of transmission slots (51, 52, 53). The terminal can transmit a return link signal (32) which is phase continuous across the transmission slots.
