Abstract: The invention relates to a method for generating a currently valid one-time release code (1) for an electronic lock (9), which can be transitioned from the locked state thereof to the released state thereof by entering the currently valid one-time release code (1). In order to provide an electronic lock (9) having very high security against unauthorized actuation, according to the invention the currently valid one-time release code (1) is generated by encrypting the immediately previously valid one-time release code (5) by means of an encrypting algorithm (6), wherein the encryption takes place in consideration of an encrypting code (4) generated from an individual master code (2) that is entered and a key code (3) that is stored in the electronics of the lock (9).

Abstract: The invention relates to a method for estimating a channel of a mobile radiotelephone channel during a multipath reception. According to said method, an interpolation of the channel coefficients which are determined on the basis of the respective impulse response, in two adjacent time intervals (slot 1 and slot 2), is carried out. Before said interpolation, the individual components of the impulse response are examined to determine whether they belong to one and the same transmission path, and an interpolation is only carried out for the components to which this applies.
