Novel Deterministic Detection and Estimation Algorithms for Colocated Multiple-Input Multiple-Output Radars

IEEE Access, 2022
In this manuscript, the problem of detecting multiple targets and estimating their spatial coordinates (namely, their range and the direction of arrival of their electromagnetic echoes) in a colocated multiple-input multiple-output radar system operating

Data-derived iterative channel estimation with channel tracking for a mobile fourth generation wide area OFDM system [PDF]

, 2003
In this paper an iterative channel estimation technique for a mobile fourth generation coherent orthogonal frequency division multiplexing (OFDM) system is proposed. Coherent detection dictates that a per-subband estimate of the frequency response of the

Frequency Tracking and Parameter Estimation for Robust Quantum State-Estimation

, 2011
In this paper we consider the problem of tracking the state of a quantum system via a continuous measurement. If the system Hamiltonian is known precisely, this merely requires integrating the appropriate stochastic master equation. However, even a small

Availability and category-frequency estimation [PDF]

Memory & Cognition, 1991
Individuals judged how often examples of taxonomic categories had occurred in a study list. An availability hypothesis was tested--that frequency estimates are based on the retrieval of instances. Cued (by category names) recall of the examples served as an index of availability.

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
