Recent works have considered the feasibility of full duplex (FD) wireless communications in practice. While the first FD system by Choi et.al. relied on a specific antenna cancellation technique to achieve a significant portion of self-interference cancellation, the various limitations of this technique prompted latter works to move away from antenna(More)
The use of multiple-packet reception (MPR) in wireless networks is known to improve throughput especially in high-traffic conditions. The lack of synchronization among the nodes in random access systems introduces significant challenges toward the adoption of MPR in the PHY and the MAC design for systems using MPR. In this paper, we propose an asynchronous(More)
—Coping with collisions is one of the biggest challenges in the design of MAC algorithms for wireless networks. Recent advances in MIMO communications have provided the possibility of simple detection of colliding packets. In this paper, we introduce a new MIMO/MPR-aware cross-layer MAC/PHY design that is capable of combating collisions through the use of a(More)
Cooperative communication is a promising path to recover from performance anomaly in IEEE 802.11 networks. However, a simple solution for employing multiple relays to enhance the relay link quality has not been proposed. The main obstacle for multiple relay utilization in distributed networks is that synchronizing relay transmissions requires huge signaling(More)

—Multi-user detection is an efficient approach proposed to boost the spectral efficiency of a wireless communication system. While multiuser detection in synchronous systems or in flat fading environments has been successfully addressed, it is still an open and challenging problem in the practical case of asynchronous MIMO systems employing space-frequency(More)
—In this paper we introduce a cross-layer design between PHY and MAC for multiple packet reception (MPR). Based on the simulation results, three phases of operation has been identified for MPR-PHY/MAC design depending on the offered load to the network. The design is suitable for multi-hop ad-hoc networks. The heterogeneous nature of the colliding packets(More)
