In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offl...

Delay Limited Capacity of Ad hoc Networks: Asymptotically Optimal Transmission and Relaying Strategy
13 years 10 months ago
— The delay limited capacity of an ad hoc wireless network confined to a finite region is investigated. A transmission and relaying strategy making use of the nodes’ motion t...
