Angle of Arrival Estimation for Broadband Signals: A Comparison [PDF]
IET Intelligent Signal Processing Conference 2013 (ISP 2013), 2013 This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix approach, and an auto-focussing based version of coherent signal subspace estimation applied to MUSIC.

A New Class of Broadband Arrays With Frequency Invariant Beam Patterns [PDF]
, 2004 In this paper, a new class of broadband arrays with frequency-invariant beam pattern is proposed. By suitable substitutions, the beam pattern of a continuous sensor array with continuous temporal processing can be regarded as the Fourier transform of its

Broadband angle of arrival estimation methods in a polynomial matrix decomposition framework [PDF]
, 2013 A large family of broadband angle of arrival estimation algorithms are based on the coherent signal subspace (CSS) method, whereby focussing matrices appropriately align covariance matrices across narrowband frequency bins.

RF Spectrum Sensing Based on an Overdamped Nonlinear Oscillator Ring for Cognitive Radios
Sensors, 2016 Existing spectrum-sensing techniques for cognitive radios require an analog-to-digital converter (ADC) to work at high dynamic range and a high sampling rate, resulting in high cost.

RESEARCH OF SOME PROPERTIES OF ALPHABETS BASED ON MUTUALLY ORTHOGONAL BROADBAND SIGNALS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2019 The paper presents preliminary studies and analysis of some properties of alphabets built on the basis of the broadband signal symbols. We study the broadband signal alphabets characters and separate broadband signal symbols.
