TLDR
A geometrically based model for single bounce multipath components in line-of-sight (LOS) microcell radiowave propagation channels and has been used extensively in a study of code division multiple access (CDMA) cellular radio systems employing adaptive antennas and switched beam systems at the base station.Abstract:
This paper provides a geometrically based model for single bounce multipath components in line-of-sight (LOS) microcell radiowave propagation channels. The model characterizes the excess delay, direction-of-arrival, and received power of multipath components and is particular useful for microcell and PCS systems with low transmitter and receiver antenna heights. The model includes analytical expressions for the probability density functions for all critical channel parameters and is thus useful for analytical purposes. The model is also useful for simulating both wideband and narrowband systems and in particular the model has been used extensively in a study of code division multiple access (CDMA) cellular radio systems employing adaptive antennas and switched beam systems at the base station.read more

Geometric model for DSPN satellite reception in the dense scatterer mobile environment
F. Amoroso,W.W. Jones +1 more
TL;DR: A geometric propagation model is developed for simulating the reception of direct sequence pseudonoise satellite signals by a directional or omni directional antenna in the dense scatterer mobile environment and the results suggest a general, frequency domain interpretation for the value of DSPN in mitigating multipath fading.
