Identifiability Analysis of Sensor Arrays with Sensors off Half-Wavelength Grid

Md. Waqeeb T. S. Chowdhury, Yimin D. Zhang, Wei Liu, Maria S. Greco

ICASSP 2024accepted

In this paper, we analyze the effect of sensor placement to the achievable number of degrees-of-freedom (DOFs) when the sensors deviate from a half-wavelength grid. More specifically, we consider two variations of a uniform linear array (ULA), namely, when one or more sensors are shifted from half-w…

Cramer-Rao Bound Analysis of Distributed DOA Estimation Exploiting Mixed-Precision Covariance Matrix

Md. Waqeeb T. S. Chowdhury, Yimin D. Zhang

ICASSP 2022accepted

In this paper, we analyze the Cramer-Rao bound of the distributed direction-of-arrival (DOA) estimation problem where the covariance matrix is formulated in a mixed-precision manner. In this scheme, the self-covariance matrix of a subarray is locally computed using the full-precision data received a…
