A MIMO receiving system includes a MIMO antenna apparatus that receives a MIMO transmission signal including at least two MIMO transmission signal streams, wherein the MIMO transmission signal includes one or more MIMO transmission channels and wherein a MIMO transmission channel carrying one or more services includes two MIMO receive signal components covering a same frequency channel and being included in different transmission signal streams. A MIMO preprocessing apparatus preprocesses the MIMO transmission signal and outputs a multiplex signal. One or more receiving apparatus receive the multiplex signal from the output signal path to use a service contained in the single multiplex signal and output a service data stream.

MIMO receiving apparatus and MIMO preprocessing apparatus

A method for detecting a signal activity on a bus comprises measuring a current on the bus, and determining a signal activity based on the measured current.

Controller and method for collision detection

A device for in-ear sound generation comprises a sound determining unit adapted to determine a first sound signal, a sound collecting unit exposed to the ear canal and adapted to collect a second sound signal, a sound correction determining unit adapted to determine a third sound signal, and a loudspeaker exposed to an ear canal and adapted to emit the third sound signal The third sound signal includes the first sound signal and a correction component, the correction component essentially corresponding to a weighted and phase-inverted signal. The phase-inverted signal is obtained by phase inversion from a difference signal essentially corresponding to a difference between the second sound signal and the first sound signal.

Device and method for in-ear sound generation

A method of operating a wireless network, including detecting at least one signal of an external radio source, by a network device of the wireless network, during normal operation of the wireless network, in which while detecting, the network device does not send data to another network device of the wireless network, and changing a communication channel or frequency band, if the at least one signal overlaps with a currently used communication channel or frequency band.
