  • Patent number: 11026058
    Abstract: A transmitter network is provided with at least two transmitters which transmit in a same frequency range. In a unicast-transmission mode of the transmitter, the transmitters transmit unicast information packets (UC) in subsequent first time intervals. The at least two transmitters further simultaneously transmit in a broadcast mode or multicast mode, respectively, broadcast- or multicast information (BC/MC) in second time intervals that lie in between first time intervals, the broadcast information or multicast information, respectively, transmitted by the transmitters in a second time interval being substantially equal and being transmitted by the transmitters substantially time synchronous. The invention also relates to a transmitter and a receiver in the transmitter network.

  • Patent number: 10951444
    Abstract: A receiver arrangement for receiving a wirelessly transmitted HF transmission signal includes a first conversion unit for converting the HF transmission signal into a baseband information signal. Furthermore, an extraction unit is provided for extracting IQ data from the baseband information signal. A second conversion unit converts the IQ data into a further transmission signal. Additionally, a transmitter is provided for wirelessly transmitting the further transmission signal to a consumer electronics receiver unit. For normal reception of the HF transmission signal, the consumer electronics receiver unit is provided with a first antenna arrangement for receiving the HF transmission signal, and further includes a first signal processing stage for converting the HF transmission signal into IQ data, which are comprised in the HF transmission signal, and a second signal conversion stage for processing the IQ data into an output information signal of the consumer electronics receiver unit.
