Abstract: A communication system includes a plurality of transmitters and a receiving unit. The transmitters are configured to divide signals to be emitted into K part signals and to emit the K part signals using K sub-carriers. K is an integer. The K sub-carriers are frequency bands having a sub-carrier bandwidth and are spaced in frequency. The receiving unit is configured to receive signals emitted by the transmitters. The invention further refers to a transmitter.

Abstract: Disclosed herein is a transceiver for a satellite, where the transceiver includes a receiver, a digital data stream processor and at least one transmitter. The receiver is configured to receive an uplink data stream from a satellite gateway or another satellite where the data stream carries a plurality of data packets.

Abstract: A heat-conductive connection arrangement for connecting a printed circuit board to a cooling body. The connection arrangement has a carrier which is flat. At least part of the carrier includes at least one balloon body which faces away from the carrier and is connected to the carrier. The balloon body includes an envelope which encloses an interior, and the interior is at least in part filled with a preferably free-flowing, in particular viscous, heat-conducting substance. The envelope is configured so as to tear open under the influence of pressure and to thus release the heat-conducting substance.

Abstract: A receiver has an input for an incoming signal, the incoming signal possibly having a wanted signal and one or more interference signals. The receiver further has a signal source for providing a predetermined signal that is substantially identical to at least a portion of at least one interference signal of the one or more interference signals. The receiver also has a signal analyzer for analyzing the incoming signal regarding at least one known signal component of at least one of the one or more interference signals to obtain at least one interference signal parameter. A cancellation signal generator generates a cancellation signal on the basis of the at least one interference signal parameter. The receiver further has an interference canceller for at least partially cancelling the at least one interference signal by applying the cancellation signal to the incoming signal. A corresponding transmitter and a method for interference cancellation are also disclosed.
