Abstract
Method for wireless information transfer, in particular for mobile communications, in which an input signal (s.sub.1, g.sub.4) is subjected to a modulation in a transmitter (2 to 8) and reaches a receiver (11 to 15) through a transmission channel, whereby angle modulated pulses, carrying information and possessing a frequency spectrum, are generated in the transmitter in such a way that they can be time compressed in a receiver by means of a filter (13) with frequency dependent, differential delay time, also known as group delay, in such a way, that pulses arise with shortened duration and increased amplitude compared to the emitted pulses, and at least a portion of the information is imprinted onto the pulses using an additional modulation, independent of the angle modulation, and/or is used for controlling a parameter of the angle modulation that can then be registered in the receiver.
