WebJan 29, 2024 · In this paper, we propose multi-input multi-output (MIMO) beamforming designs towards joint radar sensing and multi-user communications. We employ the Cramér-Rao bound (CRB) as a performance metric of target estimation, under both point and extended target scenarios. We then propose minimizing the CRB of radar sensing while … http://theoryandpractice.org/stats-ds-book/statistics/cramer-rao-bound.html

Massive MIMO-OFDM Systems with Low Resolution ADCs: Cramér-Rao Bound …
The Cramér–Rao bound is stated in this section for several increasingly general cases, beginning with the case in which the parameter is a scalar and its estimator is unbiased. All versions of the bound require certain regularity conditions, which hold for most well-behaved distributions. These conditions are listed … See more In estimation theory and statistics, the Cramér–Rao bound (CRB) expresses a lower bound on the variance of unbiased estimators of a deterministic (fixed, though unknown) parameter, the variance of any such estimator is at … See more Multivariate normal distribution For the case of a d-variate normal distribution the Fisher information matrix has elements where "tr" is the See more • FandPLimitTool a GUI-based software to calculate the Fisher information and Cramér-Rao lower bound with application to single-molecule microscopy.
