Sparsity Order Estimation from a Single Compressed Observation Vector
Sebastian Semper, Florian Römer, Thomas Hotz +1
We investigate the problem of estimating the unknown degree of sparsity from compressive measurements without the need to carry out a sparse recovery step. While the sparsity order…
On the SNR Variability in Noisy Compressed Sensing
Anastasia Lavrenko, Florian Roemer, Giovanni Del Galdo +1
Compressed sensing (CS) is a sampling paradigm that allows to simultaneously measure and compress signals that are sparse or compressible in some domain. The choice of a sensing ma…
Design and Analysis of Compressive Antenna Arrays for Direction of Arrival Estimation
Mohamed Ibrahim, Venkatesh Ramireddy, Anastasia Lavrenko +6
In this paper we investigate the design of compressive antenna arrays for direction of arrival (DOA) estimation that aim to provide a larger aperture with a reduced hardware comple…
Performance analysis of multi-dimensional ESPRIT-type algorithms for arbitrary and strictly non-circular sources with spatial smoothing
Jens Steinwandt, Florian Roemer, Martin Haardt +1
Spatial smoothing is a widely used preprocessing scheme to improve the performance of high-resolution parameter estimation algorithms in case of coherent signals or if only a small…
Deterministic Cramer-Rao bound for strictly non-circular sources and analytical analysis of the achievable gains
Jens Steinwandt, Florian Roemer, Martin Haardt +1
Recently, several high-resolution parameter estimation algorithms have been developed to exploit the structure of strictly second-order (SO) non-circular (NC) signals. They achieve…
R-dimensional ESPRIT-type algorithms for strictly second-order non-circular sources and their performance analysis
Jens Steinwandt, Florian Roemer, Martin Haardt +1
High-resolution parameter estimation algorithms designed to exploit the prior knowledge about incident signals from strictly second-order (SO) non-circular (NC) sources allow for a…
