Properties of Time-Variant Convolutionf a time-invariant system is the response to an input Dirac impulse . If the system is excited by the time-shifted Dirac impulse ., the response . also incorporates a shift without changing its original shape.

Statistical Description of Wireless Multipath ChannelIn the following, we are going to describe the time variance of a multipath channel by statistical parameters. We assume a multipath channel with delay spread function . given in (.) and neglect the receiver noise in the following. For the receive signal (.), then holds with (.) and .. .As can be seen, even for a constant transmit signal

ApplicationsIn the following, we consider some examples to show the impact of the Doppler spread function . of a time-variant system on the output spectrum . for a given input spectrum .. As already pointed out, . is not just limiting the input spectrum in .- and .-direction.
