摘要： A method and a system for medium access control among devices in a communication system is provided. One implementation involves selecting a contention-based control period for access to a shared communication medium; dividing the contention-based control period into multiple time slots, wherein each slot has a duration that is a function of one or more of the duration of transmission of a request to send (RTS) frame, the duration of transmission of a clear to send (CTS) frame, and an inter frame space (IFS) duration therebetween; and transmitting an RTS frame in a selected slot for allocating a reservation period for accessing the medium for data transmission.

摘要： A power line communication (PLC) bridge circuit consistent with certain embodiments has a first coupler that couples data signals to and from the first power line circuit and a second coupler that couples data signals to and from the second power line circuit. The first and second power line circuits are fed AC power from separate legs of a distribution transformer, and share a single neutral connection. A first communication transceiver is connected to the first coupler for transferring data signals to and from the first coupler. A second communication transceiver is connected to the second coupler for transferring data signals to and from the second coupler. A controller examines data signals from the first transceiver and determines if the data is destined for the second transceiver, wherein data that is not destined for the second transceiver is considered local data. The controller further examines data signals from the second transceiver and determines if the data is destined for the first transceiver, wherein data that is not destined for the first transceiver is also considered local data. A bridge circuit passes data signals between the first communication transceiver and the second transceiver when the controller determines that the data is not local, and does not pass data signals between the first communication transceiver and the second communication transceiver when the controller determines that the data is local. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A method and a bit stream decoding unit for bit stream decoding has a bit stream comprising a number of consecutive samples. In order to provide for rapid and, in particular, reliable decoding of the bit stream, a detection window comprising a number of samples is defined and the detection window is positioned at certain positions on the bit stream in order to comprise certain samples with respective sample values. A majority voting is applied to the sample values in the detection window and, in dependence on the result of the majority voting, the bit stream is decoded and respective bit values are generated.

摘要： In a slotted ring network, a node may transmit a non-renewable slot reservation with any unreserved slot. The reservation restricts other nodes from transmitting a new packet in the slot. When the slot returns around the ring to the reserving node, the slot will be available. Preferably, reservation is made responsive to a starvation condition in the reserving node, which may be detected in any of various ways. In an optional enhancement, a reservation identifies the reserving node, and another node on the ring is free to transmit a new packet in the reserved slot if the new packet will reach its destination at or before the reserving node, and thus will not interfere with the reservation.

摘要： A method for resolving a collision in a communication system using medium access control based on contention. The method enables management and control of a contention window size of each mini slot and thus all the terminals may have an equal opportunity to access each mini slot. Moreover, when two or more terminals have simultaneously attempted to access any one mini slot and thus collision has occurred in the mini slot, the method restricts the access of the mini slot to the terminal or terminals that had experienced collision, and then permits an access attempt of another terminal after all the terminals which had experienced collision succeed in accessing a mini slot.

摘要： A method is described for establishing one user from multiple users of a data network as a pilot master for emitting a pilot signal, to which the other users of the data network may synchronize themselves. In the related art, a pilot signal is typically generated by a separate pilot signal generator or a permanently predefined selected user. However, this has the disadvantage that if the pilot signal generator or the selected user malfunctions, synchronization and therefore also communication of the users with one another via the data network is no longer possible. In order to avoid this disadvantage, it is suggested that at least two of the users of the data network be implemented to be pilot-master-capable and one of them assume the pilot mastership according to a described method.
