Sample Space-Time Covariance Estimation


Estimation errors are incurred when calculating the sample space-time covariance matrix. We formulate the variance of this estimator when operating on a finite sample set, compare it to known results, and demonstrate its precision in simulations. The variance of the estimation links directly to previously explored perturbation of the analytic eigenvalues and eigenspaces of a parahermitian cross-spectral density matrix when estimated from finite data.

Super-Resolution DOA Estimation for Arbitrary Array Geometries Using a Single Noisy Snapshot


We address the problem of search-free DOA estimation from a single noisy snapshot for sensor arrays of arbitrary geometry, by extending a method of gridless super-resolution beam-forming to arbitrary arrays with noisy measurements. The primal atomic norm minimization problem is converted to a dual problem in which the periodic dual function is represented with a trigonometric polynomial using truncated Fourier series. The number of terms required for accurate representation depends linearly on the distance of the farthest sensor from a reference.

AN LS LOCALISATION METHOD FOR MASSIVE MIMO TRANSMISSION SYSTEMS


We present a novel localization method based on directional beams,
as available in novel massive MIMO transmission techniques instead
of radius information, and derive a least squares (LS) estimation
method. The new method is a direct LS method that can be solved by
a linear set of equations rather than an iterative method required for
radius information. In a further step, we also show how to transform
radius information into virtual beams to apply the proposed method.
Finally, we evaluate the accuracy of the new methods by simulations.

Toeplitz Matrix Completion for Direction Finding Using a Modified Nested Linear Array


A modified nested linear array (MNLA) has been reported recently for a greater potential in increasing the degree-of-freedom. However, there exist some “holes” in the difference co-array, which results in missing “lags” and limited performance of direction-of-arrival (DOA) estimation. In order to tackle this problem, this paper applies a Toeplitz matrix completion technique to MNLA, and investigates the performance of DOA estimation on this basis. Particularly, a semidefinite program with trace minimization is derived to obtain the covariance matrix with Hermitian and Toeplitz structure.

Subspace-Based Imaging Using Only Power Measurements


In this paper, we are interested in the high-resolution
imaging of an unknown area based on only power measurements
of a small number of wireless transceivers located on one
side of the unknown area. In order to do so, we propose a
framework that achieves a polynomial order reduction in the
number of antennas required for high-resolution imaging. More
specifically, we show that by spacing the antennas at multiples
of the wavelength and applying subspace-based analysis, we can
image M targets using only 2M+1 transmit/receive antennas (as

Symmetric Sparse Linear Array for Active Imaging


Sparse sensor arrays can achieve significantly more degrees of freedom than the number of elements by leveraging the co-array, a virtual structure that arises from the far field narrowband signal model. Although several sparse array configurations have been developed for passive sensing tasks, less attention has been paid to arrays suitable for active sensing. This paper presents a novel active sparse linear array, called the Interleaved Wichmann Array (IWA). The IWA only has a few closely spaced elements, which may make it more robust to mutual coupling effects.
