A survey of indoor propagation characteristics is presented, including different models for
path loss, shadowing and fast fading mechanisms, different channel parameters including …

Concerning the design and planning of new radio interfaces for the fifth-generation (5G)
systems, this paper presents a useful contribution to the characterization of the wideband …

In emerging heterogeneous networks, small-cell base stations deployed along urban streets
can increase the network capacity for vehicular access significantly. To fully exploit the …

Multiple-input-multiple-output (MIMO) technologies allow high data rates to be obtained, but
they suffer from interantenna correlation caused by the limits in interantenna spacing …

Based on a planar and compact antenna, extensive measurements are conducted to
investigate the behavior of the colocated tri-polarized multiple-input multiple-output (MIMO) …

A method is proposed to estimate the direction of a radio-frequency transmitter with a mobile
single-antenna receiver. By considering the received signal at several points along its …

In this paper, a new method based on estimation and line-of-sight (LOS) detection of
individual time-of-arrival (TOA) measurement and Kalman filter (KF) is proposed to track a …

Wireless channel characterization is of critical importance in providing reliable tools for link
budget prediction and estimation of wireless propagation, particularly in the case of an …

This chapter is dedicated to radio channel modeling for 4G networks. In addition to recent
results in the area of 4G channel modeling at large, including complex environments such …

Multipolarized antenna systems are able to reduce equipment size while maintaining low
interantenna correlation and are thus attractive for mobile-to-mobile (M2M) wireless …
