Abstract: In a method for transmitting a data stream in a digital transmission system, the data stream is transmitted in a transmitted signal using successive OFDM symbols; a number of OFDM symbols are combined in a transmission frame; a number of transmission frames are transmitted in one transmission superframe; each transmission superframe has an information block having one or more OFDM symbols in an established position of the transmission superframe; a first transmitted signal having a first data stream in a first carrier frequency range and a second transmitted signal having a second data stream having the same information content as the first data stream are transmitted in a second carrier frequency range; and the time duration of the transmission superframes of the first transmitted signal is an integer multiple of the time duration of the transmission superframes of the second transmitted signal.

Abstract: In a method for error correction of packet data, in particular DAB data packets, code words being used over multiple data packets, redundancy information for error correction is added while maintaining the original packet data structure, at the cost of a free data field or a useful data field. The cycle of the error protection is selected as a multiple of a minimum size for a packet length.

Abstract: A method for operating a reciprocating positive displacement pump for the simultaneous low-pulsation discharge of a plurality of liquids, having for each liquid at least two pump chambers and displacement devices capable of movement therein, of which the one displacement device takes in liquid during the actual discharge phase of the other displacement device, and at the end of its intake stroke reverses its direction of movement, and, in a pre-compression phase, pre-compresses the liquid taken into the associated pump chamber and when a predeterminable pre-compression pressure has been achieved comes to a standstill, and remains at the standstill until the other displacement device has ended its liquid discharge, and, subsequent to this discharge, begins its own discharge. The method includes the steps of carrying out a pressure compensation during the subsequent discharge stroke preventing a pressure compensation between the individual pump chambers during the subsequent discharge stroke.

Abstract: For error correction of program-associated data in frames, e.g., DAB data packets, with code words being used over multiple data packets, redundancy information for error correction is added while retaining the original frame structure. The information about the length of the program-associated data is additionally protected by a code.

Abstract: A method is presented for the coded modulation of digital data, a modulation being carried out that is coded in multiple stages. In this context, the useful bits for the coded modulation are divided into parallel signal streams, and each signal stream is fed to a specific coder to carry out the channel coding. In the respective coder, the useful bits have tail bits added to them, which, in contrast to the useful bits, are channel-coded using a variable code rate, to achieve a preestablished bit number for a specific coder, so that all signal streams that are coded in parallel contain the same number of bits.

Abstract: The invention relates to a strapper for bank notes and a bank note processing apparatus having such a strapper. Especially reliable and fast strapping is possible if a guide for forming a strap loop around a bank-note bundle to be strapped that is brought into an inside area surrounded by the guide has elements for holding the strap only in its lateral edge areas when it is inserted into the guide, and when the strap is pulled it can be pulled together tightly out of the guide into the inside area around the bank-note bundle located therein.
