Abstract :
We consider the problem of finding pulses that suffer from minimum distortion when transmitted over an underspread time-varying multipath propagation channel. Mathematically, this corresponds to the design of properly time/frequency localized functions that are approximate eigenfunctions of the channel. We consider the problem of determining this localization in terms of the channel´s spreading function (deterministic case) and scattering function (stochastic WSSUS case).
