A new stochastic spatio-temporal propagation model (SSTPM) for mobile communications with antenna arrays [PDF]
, 2001 In order to evaluate the performance of third-generation mobile communication systems, radio channel models are required. The models should be capable of handling nonstationary scenarios with dynamic evolution of multipath. In this context and due to the

Directive Antenna Clutter Loss in Slant Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

Exploiting the Path Propagation Time Differences in Multipath Transmission with FEC [PDF]
, 2008 We consider a transmission of a delay-sensitive data stream from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet.

GNSS Multipath Error Modeling and Mitigation by Using Sparsity-Promoting Regularization
IEEE Access, 2019 In high-accuracy global navigation satellite system (GNSS) positioning applications, the multipath is one of the primary error sources because it is hard to parameterize. Being somewhat systematic rather than purely random, the multipath should be viewed

Multipath Parameter Estimation from OFDM Signals in Mobile Channels
, 2010 We study multipath parameter estimation from orthogonal frequency division multiplex signals transmitted over doubly dispersive mobile radio channels. We are interested in cases where the transmission is long enough to suffer time selectivity, but short ...
