This paper introduces a review article on indoor localization techniques and technologies.
The paper starts with current localization systems and summarizes comparisons between …

The quintessential goal of sensor array signal processing is the estimation of parameters by
fusing temporal and spatial information, captured via sampling a wavefield with a set of …

Array processing involves manipulation of signals induced on various antenna elements. Its
capabilities of steering nulls to reduce cochannel interferences and pointing independent …

The use of smart antennas to increase mobile communications channels has re-ignited
research and development in the field. Practicing engineers are eager to discover more …

A unified approach is presented to the related problems of recovering signal parameters
from noisy observations and identifying linear system model parameters from observed …

This paper examines the asymptotic performance of MUSIC-like algorithms for estimating
directions of arrival (DOA) of narrowband complex noncircular sources. Using closed-form …

In the present paper we investigate methods related to both the Singular Spectrum Analysis
(SSA) and subspace-based methods in signal processing. We describe common and …

In the field of civil engineering, sounding the top layer of carriageways, ie, the pavement
layer, is classically performed using standard ground-penetrating radar (GPR), whose …

Classical methods of DOA estimation such as the MUSIC algorithm are based on estimating
the signal and noise subspaces from the sample covariance matrix. For a small number of …

In antenna array applications, the propagation environment is often more complicated than
the ordinarily assumed model of plane wavefronts. Here, a low-complexity algorithm is …
