    Abstract: An apparatus and method demapping a demapping input data stream having a channel bandwidth received in a multi-carrier broadcast system into a demapping output data stream. A stream demapping mechanism demaps second frames from the demapping input data stream, and a frame demapping mechanism demaps the second frames including a preamble portion and a payload portion into the demapping output data stream. The frame demapping mechanism demaps signalling data from the preamble portion, which includes at least one preamble symbol carrying at least one preamble signalling block including signalling data, and demaps data blocks of the demapping output data stream from the payload portion by using signalling information. Payload data are mapped onto the payload portion including plural data symbols carrying payload data of at least two mapping input data streams, the payload portion being segmented into data segments each covering a bandwidth portion of the channel bandwidth.

    Abstract: An OFDM generation apparatus and methods for generating OFDM transmission signals from OFDM symbols, each including a plurality of OFDM subcarriers, for transmission in a multi-carrier data transmission system, is provided. The provided apparatus and method may use a selected mixing frequency for mixing complex time-domain samples of OFDM symbols from a baseband frequency up to a passband frequency to obtain OFDM transmission signals, wherein the mixing frequency is selected such that common phase rotations of the OFDM subcarriers of OFDM symbols with respect to adjacent OFDM symbols of the OFDM transmission signals are avoided or compensated after the mixing. Additional apparatuses and methods for avoidance or compensation of such common phase rotations are also provided.

    Abstract: In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device requests association with the network and the central controller does not support the profile of the new device. A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller passes the control functionality to the controller-capable device, which becomes the new central controller. Thus it is possible to associate the new device with the net work. The invention allows to integrate devices supporting different profiles into a common network.
