Interface module and method for configuring and parameterizing a field bus user, wherein to facilitate a configuration and parameterization of a field bus user logical addresses on the side of an engineering system are transformed with a transformation device into virtual addresses, where whether virtual addresses are present in a received virtual configuration file is recognized in an interface module via a recognition device, a signal is triggered when addresses are present in the received virtual configuration file to ensure the virtual configuration file is adopted and stored in a non-volatile manner in a configuration store within the interface module, and where the virtual addresses are transformed in the interface module via a reverse transformation device back into physically present addresses, whereby for a data exchange of the process data of the module slot, on request by further field bus users, the process data in the module slot is addressed.

A hardware accelerator module is driven by a system processor via a system bus to sequentially process data blocks of a data stream as a function of a parameter set defined by the processor. The module includes a register block adapted to receive parameter sets from the system processor, an accelerator core adapted to receive streaming data, to process data blocks of said streaming data in a manner defined by a parameter set, and to output processed streaming data, and a parameter buffering block adapted to consecutively store a plurality of parameter sets and to sequentially provide the parameter sets to the hardware accelerator core as a function of a busy state of the hardware accelerator core. The parameter buffering block enables to reduce downtimes of hardware accelerators, to increase data throughput, and to reduce the risk of a processor overload in a processor which drives several hardware accelerators.

A method transmits a message by radio from a transmitter to a receiver. In a first step, the transmitter transmits the message to a forwarding station. In a second step, the message is subsequently transmitted at the same time from the transmitter and the forwarding station to the receiver. A transmitter carries out the method.

In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3generation mobile radio networks.

Method and radio station for data transmission

In order to compatibly adapt a wireless telecommunication system with a CDMA, FDMA and TDMA multiple access component, particularly a hybrid &ldquo;JD-CDMA&rdquo; telecommunication system with respect to multiple access methods, to a GSM-specific/DECT-specific (micro-cell, macro-cell and/or Pico cell-specific) telecommunication system with respect to the air interface, signaling information fashioned as &ldquo;stealing flag&rdquo; for distinguishing between payload and signaling channels are first arranged such in a provided time slot structure that an asymmetrical division of the time slot data arises with respect to a training data block (midamble) of the time slot structure and, second, the transmission time duration for the provided time slot structure of a data element fashioned as &ldquo;chip&rdquo; and contained in the time slot structure is dimensioned such that this is a multiple of a predetermined clock frequency&mdash;for example, GSM/DECT-specific clock frequency&mdash;covering the numerical range from 5 through 7.

In a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for a transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which data channels can be distinguished by use of individual spread codes. A finite burst containing data symbols and at least one midamble with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and a ratio of a length of the midamble and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3 generation TD/CDMA mobile radio networks.

Data is transmitted via a radio interface in a radio communications system in that at least one subscriber signal is transmitted, which has an individual fine structure applied to it and, in addition to data symbols in data sections, contains a midamble with known symbols. The fine structures of the data sections and of the midamble differ. At the transmission end, a sum signal is produced which contains signal sections to which different fine structures are applied. The sum signal is filtered in at least one transmission filter and is transmitted via a transmission channel to a receiving radio station. A control device controls the addition so that different attenuation of the signal sections is compensated for by the filtering. The method is suitable, in particular, for mobile stations having a single or variable data rate, and for base stations for use in 3rd generation TD/CDMA mobile radio networks.
