Modelling and Simulation of GPS Multipath Propagation
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020Multipath introduces error into the Global Positioning System (GPS) accuracy, which is difficult to mitigate. This paper aims to review the multipath propagation and its effect on GPS applications, through the modeling of a single reflected signal propagation behavior.

A statistical model of urban multipath propagation
IEEE Transactions on Vehicular Technology, 1972An urban multipath propagation experiment, involving the simultaneous transmission from a fixed site of 100-ns pulses at 488, 1280, and 2920 MHz and their reception at a mobile van, is described. A statistical analysis of the data in the resulting multipath responses is given and used as a basis for a statistical model of urban multipath propagation.

Strange attractors in multipath propagation
IEEE Transactions on Communications, 1991The estimation of the correlation dimension of multipath propagation signals in an indoor environment, indicates the presence of a strange attractor of dimension between four and five, suggesting deterministic chaos. The authors stress that although the profiles they examined show saturation in all three experimental configurations, indicating that ...

Wideband multipath measurements at 1300 MHz have been made in five factories in Indiana. The RMS delay spread ( sigma ) values were found to range between 30 ns and 300 ns. Median sigma values were 96 ns for line-of-sight (LOS) paths along aisleways and 105 ns for obstructed paths across aisles.

Effects of Multipath Propagation on Digital Radio
IEEE Transactions on Communications, 1981This paper summarizes experimental work at Bell Laboratories in the field of multipath propagation as it affects digital radio. Field and laboratory measurements are presented on commercial-quality high-speed digital radio systems working in the 4, 6, and 11 GHz common carrier bands. Circuits and equipment used in these systems are all state of the art,

Propagation Characteristics of Dense Multipath Components
IEEE Antennas and Wireless Propagation Letters, 2010The dense multipath components (DMC) represent the part of the radio channel that cannot be characterized by a superposition of distinct plane waves, i.e., the specular components (SC). In this letter, the propagation characteristics of the DMC are analyzed in indoor environments from two perspectives. First, the proportion of DMC in the total power is

An adaptive antenna for a multipath propagation environment
ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002A multipath propagation environment is inevitable in mobile radio. Frequency-selective fading is serious hindrance in high-speed TDMA transmission because the delay difference between multipath signals is large in comparison with the symbol duration. This paper presents a novel adaptive antenna for mobile radio.

A Statistical Model for Indoor Multipath Propagation
IEEE Journal on Selected Areas in Communications, 1987The results of indoor multipath propagation measurements using 10 ns, 1.5 GHz, radarlike pulses are presented for a medium-size office building. The observed channel was very slowly time varying, with the delay spread extending over a range up to about 200 ns and rms values of up to about 50 ns. The attenuation varied over a 60 dB dynamic range.
