Success probability of the Babai estimators for box-constrained integer linear models
Jinming Wen, Xiao-Wen Chang
In many applications including communications, one may encounter a linear model where the parameter vector $\hbx$ is an integer vector in a box. To estimate $\hbx$, a typical metho…
An Efficient Algorithm for Optimally Solving a Shortest Vector Problem in Compute-and-Forward Protocol Design
Jinming Wen, Baojian Zhou, Wai Ho Mow +1
We consider the problem of finding the optimal coefficient vector that maximizes the computation rate at a relay in the compute-and-forward scheme. Based on the idea of sphere deco…
Mobile Localization in Non-Line-of-Sight Using Constrained Square-Root Unscented Kalman Filter
Siamak Yousefi, Xiao-Wen Chang, Benoit Champagne
Localization and tracking of a mobile node (MN) in non-line-of-sight (NLOS) scenarios, based on time of arrival (TOA) measurements, is considered in this work. To this end, we deve…
Distributed Cooperative Localization in Wireless Sensor Networks without NLOS Identification
Siamak Yousefi, Xiao-Wen Chang, Benoit Champagne
In this paper, a 2-stage robust distributed algorithm is proposed for cooperative sensor network localization using time of arrival (TOA) data without identification of non-line of…
