Abstract:
An internal-combustion engine can be operated in a homogeneous charge compression ignition mode at least under certain operating conditions. The combustion mixture present in the combustion chamber reaches auto-ignition conditions and ignites itself. The internal-combustion engine includes a triggering unit for triggering the auto-ignition during the homogeneous charge compression ignition mode before the auto-ignition conditions have been reached. The triggering unit is constructed as a corona ignition system and can be operated for triggering the auto-ignition during the homogeneous charge compression ignition mode, particularly by generating a non-thermal plasma.

Abstract:
The invention relates to a data transmission method in which the data to be transmitted are divided into a plurality of subchannels each with a normal component and a quadrature component that is orthogonal to the normal component. The divided data are transmitted in different frequency bands. The frequency bands are arranged with non-equidistant frequency spacings between one another. An error signal is generated at the reception end for each subchannel both for the normal branch and for the quadrature branch and fed to a corresponding reception filter.
