In this paper, we propose an opportunistic downlink interference alignment (ODIA) for
interference-limited cellular downlink, which intelligently combines user scheduling and …

Cellular networks are becoming dense due to deployment of small cells and a number of
user devices. Such networks are called ultra-dense networks (UDNs). In this paper, we …

We introduce an opportunistic downlink interference alignment (ODIA) for interference-
limited cellular downlink, which intelligently combines user scheduling and downlink IA …

Underwater acoustic (UWA) communication suffers from large propagation delays, limited
bandwidth, frequency dependent attenuation and severe multipath fading. Low power …

In this paper, we propose a novel user scheduling that achieves the optimal multi-user
diversity gain in multi-cell uplink networks with multiple eavesdroppers. In the proposed …

We propose a decentralized multi-cell aware opportunistic random access (MA-ORA)
protocol that almost achieves the optimal throughput scaling in a K-cell random access …

It is a challenging task to design a random access protocol that achieves the optimal
throughput in multi-cell random access with decentralized transmission due to the difficulty …

In this paper, we propose an opportunistic interference alignment (OIA) technique for cellular
downlink networks, which efficiently reduces the effect of inter-cell interference from base …

This paper studies multiuser diversity of uplink MIMO cognitive radio network and proposes
a two-stage opportunistic user scheduling scheme. In the first stage, a cognitive …

In this letter, we investigate the multi-user diversity (MUD) in an underlay cognitive radio
(CR) network where multiple secondary transmitters and primary receivers exist. Many …
