A Spreading Code MAC Protocol for Multi-Hop Wireless Ad Hoc Networks
— We propose a spreading code medium access control (MAC) protocol with each node equipped with single transceiver for wireless ad hoc networks, based on the code division multip...

Multi-hop Cooperative Wireless Networks: Diversity Multiplexing Tradeoff and Optimal Code Design
In this paper, we consider single-source, single-sink (ss-ss) multi-hop relay networks, with slow-fading Rayleigh links and single-antenna relay nodes operating under the half-dupl...

Synchronization-Aware Distributed Space-Time Codes in Wireless Relay Networks
— In this paper, we consider the design of synchronization-aware distributed space-time codes, which we denote as diagonal distributed space-time codes (DDSTC), for N relay nodes...
