摘要： A communication system (500) comprising a plurality of devices (101–106) interconnected via a bus, the bus being capable of handling isochronous and asynchronous transmissions. A status manager (105) maintains an isochronous status channel for broadcasting status information on the isochronous status channel. Devices (101–106) can send status information to the status manager (105) so it can broadcast it over the status channel. The devices (101–106) can then tap into the status channel to read the status information if they support it, or use conventional asynchronous messages to obtain the status information otherwise. Information on the status channel is only sent once, which saves bandwidth. This information can be about the network topology of the communication system (500), about capabilities of a device (101–106) in the communication system (500), about available bandwidth on the bus, or about the strength of a level of attachment between a mobile device (520) and a base station device (106) in the communication system (500).

摘要： Apparatuses are connected in a tree structure, wherein the branches correspond to bus connections between apparatuses. The apparatus at the root node the tree ultimately arbitrates access to the bus connections. The tree structure is dynamically reorganized by selecting a new root node. Selection of the new root node involves predicting a volume of messages to be sent by each of the apparatuses (preferably by counting the number of messages originating from each apparatus during an observation period). An expected heavy sender apparatus is selected as new root node. Thus, the heavy sender is able to get faster access to arbitration and network resources, reducing jitter in the time points at which messages can be sent by the heavy sender.

摘要： A receiver including a (differential-quadrature-) phase-shift-keying demodulator (4) and a differential detector (10) having a decoder (19), is provided with a non-linear compensator (20) for compensating the decoder output siqnal for (part of) an interference term, to improve the decoding process and to reduce the number of incorrect decisions. The non-linear compensator (20) includes a channel estimator (22) for estimating a coefficient of a term of the decoder output siqnal and removers (21,23) for removing the term from the decoder output signal.
