Abstract
Method for wireless information transfer, in particular for mobile communications, in which an input signal (s , g ) is subjected to a modulation in a transmitter ( to ) and reaches a receiver ( to ) 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 ( ) 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, arid/or is used for controlling a parameter of the angle modulation that can then be registered in the receiver.
