摘要： In a receiving method for mobile radio applications, a given user data signal and at least one further user data signal located within the same frequency band are received. These two user data signals are equalized with an adaptive multiuser data detector and with a multiuser channel decoder that is connected in the feeback path to the adaptive muliuser data detector. Noise-reduction in the given user data signal is achieved by taking into consideration, during channel decoding, an extrinsic information item generated during source decoding.

摘要： In a method for packet transmission using an ARQ protocol on transmission channels in a digital transmission system, for channel coding, turbo coding is carried out in a turbo coder at the transmitter end and turbo decoding is carried out in a turbo decoder at the receiver end using soft-decision output signals. A return channel is provided, which the receiver uses to request the information from faulty packets once again. An RCPTC is used as the turbo code. When the information in a faulty packet is retransmitted, at least a portion of the information suppressed by the puncturing of the RCPTC in the previous transmission is transmitted. This additional information is inserted into the already existing information at the receiver end, and this completed information is decoded once again. When the repeat transmission is made, the only bits which are transmitted are those which are additionally available at the next lower coding rate, since they are not punctured. The method is repeated, until the packet is decoded without any errors or all of the coded information in a packet is transmitted.

摘要： A voltage source with preset values of the source voltage and the internal resistance is simulated by a computing circuit (25, 26; 35, 36; 47) which calculates a reference parameter (S.sub.UO ; S.sub.IO) for a current or voltage regulator (20; 30; 40) that forms the output of the voltage source. The reference parameter (S.sub.UO ; S.sub.IO) corresponds to the output current (I.sub.O) or the output voltage (U.sub.O) and is obtained from a measured parameter (M.sub.UO ; M.sub.IO) and the input parameters (S.sub.U ; S.sub.R) which correspond to the values to be set. The measured parameter (M.sub.UO ; M.sub.IO) is derived from the output voltage (U.sub.O) or the output current (I.sub.O). When using this simulation circuit, separate high load resistors and mechanical switching contacts are unnecessary and the input parameters (S.sub.U ; S.sub.R) can be set with analog switches.
