Abstract: The influence of a DC offset with a carrier-frequency offset at the same time is reduced in that the values of the assumed or determined DC offset and of the assumed or determined carrier-frequency offset are included in the determination of reliability information for one sub-carrier in the multicarrier system, and the reliability information is corrected in this way. A factor M, where M<1, is defined for each sub-carrier on the basis of the values for the DC offset and for the carrier-frequency offset, and the reliability information for the sub-carriers is multiplied by these factors M.

Abstract: Distortions of radio signals transmitted in data blocks in an OFDM method, the distortions being caused by IQ asymmetries, can be estimated and subsequently equalized by means of specific reference data symbols which are transmitted at the transmitter end and may be part of a preamble. The method can be used particularly advantageously in a direct-mixing receiver.

Abstract: A component-insertion table is provided with a receptacle (take-up device) for the circuit carrier, a programmable adhesive dosing feeder and a programmable component dispensing unit. The receptacle containing the circuit carrier is moved coordinately below a cover of the component-insertion table to a centrally located position for the automatic application of an adhesive with the aid of the adhesive dosing feeder, as well as into a centrally located insertion position for the manual placement of the components. The adhesive-application position and the insertion position be within a window in the cover through which the individual component insertion locations on the circuit carrier are made from above in a programmed order of succession.
