Two-step ranging based on energy detection for IR-UWB sensor networks

Tongxin xuebao, 2009
In order to design a low computational and cost ranging method for the IR-UWB （impulse radio ultra wideband） wireless sensor network, a two-step DP （direct path） component TOA （time of arrival） estimation algorithm based on energy detection was proposed.
