Abstract: The invention relates to a method for equalizing a signal with a frame structure, received via a time-variable transmission channel. According to said method, a frame-type equalization is used. The channel unit pulse response is analyzed and one equalization alternative is selected from several provided alternatives. According to the principle of equalization with decision feedback, it is preferable if only two alternatives are provided; a conventional forward equalization and an inverse-time reversed equalization. A decision in favor of one or the other of these alternatives can be made simply based on the sign characterizing the so-called skewness.

Abstract: An antenna system (1) with a particularly simple Con and a steep transmission angle, for lower frequencies in the short wave range. The inventive antenna system includes two antennae (2) which are interconnected by a control unit (4) and which together form a dipole antenna. This antenna system (1) is particularly suitable for mobile operation in vehicles.
