In signal processing, direction of arrival (DOA) denotes the direction from which usually a propagating wave arrives at a point, where usually a set of sensors are located. These set of sensors forms what is called a sensor array. Often there is the associated technique of beamforming which is estimating the signal from a given direction.
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
SAMV (iterative sparse asymptotic minimum variance [1] [2]) is a parameter-free superresolution algorithm for the linear inverse problem in spectral estimation, direction-of-arrival (DOA) estimation and tomographic reconstruction with applications in signal processing, medical imaging and remote sensing.
Estimation of signal parameters via rotational invariant techniques (ESPRIT), is a technique to determine the parameters of a mixture of sinusoids in background noise. This technique was first proposed for frequency estimation. [ 1 ]
Based on the statements and interviews that have been made public so far, the news of Luigi Mangione’s arrest seems to have come as a shock to those who knew him.
Whether you're heading home after the holidays or heading on your first vacation of the new year, the busy holiday travel period continues, and weather may be a factor. For some, snow, rain ...
November retail sales grew at a faster pace than Wall Street analysts had expected, reflecting continued resilience in the American consumer and indicating that the holiday shopping season in the ...
Reduced rank methods aim to overcome the computational burdens of the direct method by reducing the dimensionality of the data or the rank of the interference covariance matrix. [2] This can be accomplished by forming beams and performing STAP on the beamspace. [7] Both pre and post Doppler methods can be used in the beamspace.
