Network localization is a key feature in many wireless services and applications. In typical rang-based localization techniques, “agents” try to perform position estimation through ranging with respect to “anchors” with known positions. Based on the definition of squared positional error bound (SPEB), the localization accuracy can be determined by the transmit power, carrier frequency and signal bandwidth,...
Bandlimited optical intensity channels, such as visible light communication (VLC) systems, require that all signals satisfy a bandwidth constraint as well as average and non-negativity amplitude constraints. In this paper, a two-dimensional signal space for optical intensity channels is presented in which all signals are strictly bandlimited. A novel feature of this model is that the strict non-negativity...
