Quantize-and-Forward Relaying with M-ary Phase Shift Keying
Abstract—Using cooperative transmission, two or more singleantenna users can share their antennas to achieve spatial diversity in a slow fading channel. One relaying protocol tha...

Optimal Packet Scheduling in an Energy Harvesting Communication System
We consider the optimal packet scheduling problem in a single-user energy harvesting wireless communication system. In this system, both the data packets and the harvested energy ...

Frequency-Domain Eigenbeam-SDM and Equalization for High Speed Data Transmissions
— In wireless communications, the channel consists of many resolvable paths with different time delays, resulting in a severely frequency-selective fading channel. The frequencyd...

Link-layer salvaging for making routing progress in mobile ad hoc networks
IEEE 802.11 MAC, called the Distributed Coordination Function (DCF), employs carrier sensing to effectively avoid collisions, but this makes it difficult to maximally reuse the sp...
