Distributed Opportunistic Scheduling With Two-Level Probing
Distributed opportunistic scheduling (DOS) is studied for wireless ad-hoc networks in which many links contend for the channel using random access before data transmissions. Simpl...

Dual-hop adaptive packet transmission systems with regenerative relaying
We propose and analyze two different approaches for performing adaptive modulation and coding (AMC) in dualhop transmission systems, where a source node S communicates with a certa...

MMSE Based Transceiver Designs in Closed-Loop Non-Regenerative MIMO Relaying Systems
In this paper, we propose a new design strategy based on the minimum mean-squared error (MMSE) in closedloop non-regenerative multiple-input multiple-output (MIMO) relaying system...

Joint channel estimation and resource allocation for MIMO systems-part I: single-user analysis
Multiple antenna systems are known to provide very large data rates, when the perfect channel state information (CSI) is available at the receiver. However, this requires the recei...
