Bursty transmission and glue pouring: on wireless channels with overhead costs
Power efficiency is a capital issue in the study of mobile wireless nodes owing to constraints on their battery size and weight. In practice, especially for low-power nodes, it is ...

Bandwidth scaling for fading multipath channels
Abstract--We show that very large bandwidths on fading multipath channels cannot be effectively utilized by spread-spectrum systems that (in a particular sense) spread the availabl...

Optimality of beamforming for MIMO multiple access channels via virtual representation
In this paper, we consider the optimality of beamforming for achieving the ergodic capacity of multiple-input multiple-output (MIMO) multiple access channel (MAC) via virtual repre...

An Achievable Rate Region for the Broadcast Channel with Feedback
A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with noiseless or noisy feedback. The coding strategy involves block-...
