Effects of Channel Models and Rake Receiving Process on UWB-IR System Performance
Abstract— In ultra-wideband impulse radio (UWB-IR) systems, multipath-delayed received pulses may overlap if two consecutive multipaths arrive within less than the pulse duration...

Scaling communication-intensive applications on BlueGene/P using one-sided communication and overlap
In earlier work, we showed that the one-sided communication model found in PGAS languages (such as UPC) offers significant advantages in communication efficiency by decoupling d...
