Underwater Source Localization Using TDOA and FDOA Measurements with Unknown Propagation Speed and Sensor Parameter Errors
Bingbing Zhang, Yongchang Hu, Hongyi Wang +1
Underwater source localization problems are complicated and challenging: a) the sound propagation speed is often unknown and the unpredictable ocean current might lead to the uncer…
Self-Estimation of Path-Loss Exponent in Wireless Networks and Applications
Yongchang Hu, Geert Leus
The path-loss exponent (PLE) is one of the most crucial parameters in wireless communications to characterize the propagation of fading channels. It is currently adopted for many d…
Robust Differential Received Signal Strength-Based Localization
Yongchang Hu, Geert Leus
Source localization based on signal strength measurements has become very popular due to its practical simplicity. However, the severe nonlinearity and non-convexity make the relat…
Comments on Cooperative Density Estimation in Random Wireless Ad Hoc Networks
Yongchang Hu
In Onur et al. ["Cooperative density estimation in random wireless ad hoc networks," IEEE Commun. Lett., vol. 16, no. 3, 269 pp. 331-333, Mar. 2012], two novel density estimation (…
On a unified framework for linear nuisance parameters
Yongchang Hu, Geert Leus
Estimation problems in the presence of deterministic linear nuisance parameters arise in a variety of fields. To cope with those, three common methods are widely considered: (1) jo…
