Fifth generation (5G) wireless networks face various challenges in order to support large-
scale heterogeneous traffic and users, therefore new modulation and multiple access (MA) …

The emerging massive/large-scale multiple-input multiple-output (LS-MIMO) systems that
rely on very large antenna arrays have become a hot topic of wireless communications …

Both caching and interference alignment (IA) are promising techniques for next-generation
wireless networks. Nevertheless, most of the existing works on cache-enabled IA wireless …

Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

The capacity of interference network is a fundamental issue that eludes the researchers for
decades. Interference alignment (IA) is an emerging interference management technique …

This paper presents the design and implementation of 802.11 n+, a fully distributed random
access protocol for MIMO networks. 802.11 n+ allows nodes that differ in the number of …

The use of small cells serviced by low-power base stations such as femtocells is envisioned
to improve the spectrum efficiency and the coverage of next-generation mobile wireless …

We study the achievable rate of an uplink MIMO cognitive radio system where the primary
user (PU) and the secondary user (SU) aim to communicate to the closest primary base …

We introduce an opportunistic interference alignment (OIA) for cellular networks, where a
user scheduling strategy is utilized in time-division duplexing uplink communication …

Unlicensed secondary users (SUs) in cognitive radio networks are subject to an inherent
tradeoff between spectrum sensing and spectrum access. Although each SU has an …
