Relay-Selection Improves the Security-Reliability Trade-off in Cognitive Radio Systems
Yulong Zou, Benoit Champagne, Wei-Ping Zhu +1
We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a secondary destination (SD) and multiple secondary relays (SRs) in the presence of an eavesd…
Low-Complexity Variable Forgetting Factor Constrained Constant Modulus RLS Algorithm for Adaptive Beamforming
Q. Boya, Y. Cai, B. Champagne +2
In this paper, a recursive least squares (RLS) based blind adaptive beamforming algorithm that features a new variable forgetting factor (VFF) mechanism is presented. The beamforme…
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…
