Abstract: The present invention relates to receiver apparatuses and methods of controlling weight adaptation in a receiver of a code multiplex telecommunications system with orthogonal spreading codes, wherein received discrete time signal samples are chip-level filtered by using a first equalizing step. Additionally, the received discrete time signal samples are delayed by a time period corresponding to a data symbol and used in a second equalizing step. Symbol estimates obtained from the first equalizing step are non-linearly filtered and used as a desired response for the second equalizing step in the following symbol period, wherein equalizer weights adapted in the second equalizing step are used for the first equalizing step. Alternatively, the second equalizing step may be dispensed with and weight adaptation may be incorporated in a single equalizing step.

Abstract: A method and a device for operating an internal combustion engine make it possible to set a setpoint value for the overall fresh air mass flow as the top control target. The internal combustion engine has a multi-flow air system including a multi-channel air supply and a corresponding multi-channel exhaust gas discharge, exhaust gas being recirculated from the multi-channel exhaust gas discharge into the multi-channel air supply and the exhaust gas recirculation being regulated for setting a setpoint fresh air mass flow. A value for the required overall fresh air mass flow of the internal combustion engine is predefined for at least one exhaust gas recirculation channel as the setpoint for the exhaust gas regulation.
