TL;DR: Performance of time-hopping spread-spectrum multiple-access systems employing impulse signal technology for both analog and digital data modulation formats under ideal multiple- access channel conditions is estimated.

TL;DR: The characteristics of impulse radio using a modulation format that can be supported by currently available impulse signal technology are described and analytical estimates of its multiple- access capability under ideal multiple-access channel conditions are given.

TL;DR: These findings reveal that cooperation offers diversity benefits even when cooperative relays choose not to transmit but rather choose to cooperatively listen; they act as passive relays and give priority to the transmission of a single opportunistic relay.

TL;DR: This paper describes several cooperative localization algorithms and quantify their performance, based on realistic UWB ranging models developed through an extensive measurement campaign using FCC-compliant UWB radios, and presents a powerful localization algorithm that is fully distributed, can cope with a wide variety of scenarios, and requires little communication overhead.

TL;DR: A statistical model for the ultra-wide bandwidth (UWB) indoor channel is established based on an extensive measurement campaign in a typical modern office building with 2-ns delay resolution and it is found that the correlation between multipath components is negligible.
