WebAbstract—Typically, a multipath channel response can be characterized as a sum of Rayleigh-fading ‘rays’, each deﬁned by a time delay and a mean-square amplitude. Therefore, the channel response can be largely described by a power delay proﬁle (PDP), which is the set of mean-square ray amplitudes and relative delays.
