Patent ID: 8767805

Claim:
An assembly for parallel processing of data streams by satellite communication links, comprising a first subassembly for a data transmission operation and/or a second subassembly for a test operation, the first subassembly including a modem having a number of inputs in a transmitter side, wherein a data stream can be applied to each input, and an output for a total data stream, wherein the modem has a number of signal paths connected in parallel, wherein in each signal path, a modulation stage, a stage for sampling modulated signal and a mixing stage is arranged, outputs of all mixing stages are connected to inputs of a summation stage and an output of the summation stage is connected to the output of the modem, the second subassembly having an input for actuating the second subassembly by initialization data, which is connected to a control management and multiplexing unit for controlling the test operation, the unit is connected to a downstream carrier management assembly which has a number of outputs, each output is connected to a test sequence generating unit for generating one test sequence per carrier, outputs of all test sequence generating units are connected to a parallel/serial converter assembly followed by a filter assembly, and an output of the filter assembly is connected to an output of the second subassembly.
