The polarization millimeter wave (mmWave) massive multiple-input multiple-output (MIMO)
system has been deployed in next-generation wireless communication since it can provide a …

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 …

The virtual array generation process based on typical sparse arrays is studied for a mixture
of circular and non-circular impinging signals. It consists of two sub-arrays: one is the …

In this paper, we propose a vectorized noncircular MUSIC (VNCM) algorithm based on the
concept of the coarray, which can construct the difference and sum (diff–sum) coarray, for …

In this paper, the problem of off-grid direction of arrival (DOA) estimation for the more
general case of coexisting circular and non-circular signals is investigated from the …

Statistical properties of signals play an essential role in designing algorithms for Direction of
Arrival (DoA) estimation. Many times, signals are assumed to be circular, and circular …

In this paper, we present an analytical performance assessment of 2-D Tensor ESPRIT in
terms of physical parameters. We show that the error in the-mode depends only on two …

In this paper, we estimate the Direction of Arrival (DoA) of the non-circular signals impinging
on the Non-Uniform Linear Array (NULA). A new methodology based on the fourth order …

Resolving more sources than sensors is always of interest to researchers. For this purpose,
generation of the virtual array from the non‐uniform linear array has recently gathered a lot …

Sparse arrays have attracted a lot of interests recently for their capability of providing more
degrees of freedom than traditional uniform linear arrays. For a mixture of circular and …
