Abstract: For example in case of an OFDM multicarrier transmission system the transmission characteristics of subcarriers of a multicarrier transmission system using a plurality of antenna elements (3, 3?) can be adjusted. Particularly the power and the phase of the subcarriers can be adapted. To this object the subcarrier frequency channel (2, 2?) characteristics of the multicarrier transmission are detected (11, 11?) at the side of the transmitter (3). The power of each subcarrier is then distributed by a weighting unit (14, 14?). The subcarriers can be further pre-equalized (1, 1?) by dividing the subcarrier signal respectively by the sum of the squared magnitude of the frequency channel characteristics of all subcarrier signals or a frequency characteristic of the selected antenna element (3, 3?).

Abstract: A transmitting apparatus transmits signals in a digital telecommunication system and a synchronising method is used for synchronizing such signals at a receiving apparatus. The transmitting apparatus prepares for transmission of a reference symbol having at least two repetition patterns, whereby one of the at least two repetition patterns is phase-shifted in relation to the other repetition pattern, and a synchronizing mechanism in the digital telecommunication system uses the reference symbol once received for synchronization. The synchronizing mechanism uses a cross-correlation mechanism to cross-correlate at least one of the two repetition patterns within a correlation window having a predetermined length.

Abstract: A system and method that improve service and device discovery in a UPnP-based wireless communication network and avoids unnecessary broadcast messages on a MAC sublayer of a DLC layer caused by UPnP multicast messages on an IP layer by intercepting UPnP multicast messages in a network protocol stack below the IP layer. A module intercepts multicast UDP packets destined to a UPnP IP multicast address and port, the multicast UDP packets containing UPnP packets as payload. The module executes DLC/MAC-based service discovery functions to perform wireless network-specific device discovery and to find UPnP-enabled devices in the wireless communication network. Once a wireless network device discovery has returned nodes that fulfill criteria given in the search, the module uses unicast DLC/MAC messages to send UPnP packets to only those nodes that are UPnP-enabled and whose device type matches the respective UPnP device type sought.

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.
