This book provides an excellent reference for all professionals working in the area of array
signal processing and its applications in wireless communications. Wideband beamforming …

This paper provides a broad overview of electromagnetic technologies in the context of
subsea navigation/position fixing and telemetry applications. Acoustics provides a more …

Frequency-invariant beam patterns are often required by systems using an array of sensors
to process broadband signals. If the spatial aperture is shorter than the involved …

Sparse wideband array design for sensor location optimization is highly nonlinear and it is
traditionally solved by genetic algorithms (GAs) or other similar optimization methods. This is …

A response variation (RV) element is introduced to control the consistency of an adaptive
wideband beamformer's response over the frequency range of interest. By incorporating the …

In the cases of rapidly moving interference and look-direction error, robustness and output
signal to interference and noise ratio (SINR) of conventional wideband adaptive …

It is shown in this communication that the problem of synthesizing a frequency-invariant (FI)
beam pattern with as few elements as possible can be transformed into a sequence of …

One of the most popular methods in broadband beamforming is the Frost space-time
processing. In this method, a pre-steering delay is followed by a tapped delay line (TDL) …

An application of the least squares (LS) approach to the design of frequency-invariant
beamformers is proposed, based on three different formulations of the problem. The first one …

A least squares formulation for the design of frequency invariant beamformers (FIBs) is
proposed with two solutions provided. One is based on the Lagrange multipliers method and …
