Super-Resolution Time of Arrival Estimation for a Symbiotic FM Radio Data System
IEEE transactions on broadcasting, 2020A symbiotic FM radio data system (SRDS) refers to a kind of digital broadcasting whose signal co-exists with the FM in channel. The SRDS signal has a symmetrical split spectrum in the band of the host FM signal spectrum.

An underwater sensor network localization algorithm based on Time-of-Arrivals (TOAs)
2013 Ninth International Conference on Natural Computation (ICNC), 2013The underwater sensor network localization algorithm is one of the very important steps in the underwater sensor network initialization process. Due to the deployment of environmental constraints, the underwater sensor node can only be indirectly localized by calculation.

On the impact of time-of-departure knowledge on the accuracy of time-of-arrival localization
Comput. Networks, 2020We analyze the accuracy of source localization methods based on time-of-arrival (ToA) measurements from a set of cooperating receivers (anchors). We consider three different system scenarios, with and without knowledge of the time-of-departure (ToD) at ...
