Investigation on Stochastic Tap Delay line model of UWB indoor channel

Abstract

The Stochastic Tap Delay line model of the UWB indoor channel have been used for generating Power Delay Profile (PDP). The local Power Delay profiles for different categories of channel types with range of T-R distance separation as per IEEE 802.15.4a standard have been generated. The important attributes of PDP have been selected for investigating the relative Channel behavior. The Complementary CDFs of mean excess delay and root mean square (RMS) delay spread have been computed for the four channel categories which include CM1 (0-4 m LOS), CM2 (0-4 m NLOS), CM3 (4-10 m NLOS) and extreme NLOS (6-17 m). The mean and standard deviation of the ensemble of PDPs at various locations have also been evaluated through simulations.
