A method of wireless information transfer, especially for mobile communication, whereby an input signal (sl, g4) is subjected to a modulation in a transmitter (2-8) and reaches a receiver (11-15) via a transmission channel. The transmitter produces angularly modified pulses having a frequency spectrum and carrying information, in such a way that said pulses can be time compressed in the transmitter by means of a filter (13) with a frequency dependent differential transit time, also called a group transit time, so that pulses with reduced duration and higher amplitude can arise, and at least one part of the information in the transmitter is impressed on the pulses by means of a modulation independent from the angle modulation and/or used to control an angle modulation parameter which can be detected in the receiver.
