Power delay profile

The power delay profile is a measure of the delay spread between the first and last path received and the energy or power available in each path of a multipath communication channel. It is used for modelling ITU-R channels and can be obtained through measurements to determine the main parameters of the channel. The power delay profile is used to obtain a time-varying and frequency-selective multipath channel, such as the Extended Typical Urban model developed by 3GPP.From: TCP Performance over UMTS-HSDPA Systems [2019], Fast Convolution Based Complexity Reduction in Universal Filtered Multi-Carrier Systems [2022], Engineering Electromagnetics [2019], Discrete bit-loading for OFDM systems under BER-constraint and imperfect CSI [2022]

Power Delay Profile (PDP) is defined as the power of the received signal through a wireless communication channel, as a function of time delay. The general form of PDP is given by p(τ)=∑ipiδ(τ−τi)

The ITU-R Channels are the frequency selective fading channel models. Since it is difficult to reliably test the signal in a practical situation, a power delay profile (PDP) is used for modelling the ITU-R channels. A PDP for a multipath channel gives the average received signal strength as a function of time delay as in Table 5 and Table 6.
