Cognitive radio networks (CRNs) have been widely studied to improve spectrum utilization
through a dynamic spectrum allocation scheme. However, many challenges remain and one …

Due to their large memory capacities, many modern servers require chipkill correct, an
advanced type of memory error detection and correction, to meet their reliability …

Cognitive radio (CR) has achieved increasing attention to improve the spectrum utilisation
by allowing the coexistence of primary users (PUs) and cognitive users (CUs) in the same …

In communication industry one of the most rapidly growing area is wireless technology and
its applications. The efficient access to radio spectrum is a requirement to make this …

In this paper, we investigate the resource management problem in orthogonal frequency
division multiplexing (OFDM) based multiple-input multiple-output (MIMO) cognitive radio …

We consider a multi-channel multi-user cognitive radio MIMO network in which each node
controls its antenna radiation directions and allocates power for each data stream by …

We consider the problem of maximizing the throughput of a multi-antenna cognitive radio
(CR) network. With spatial multiplexing over each frequency band, a multi-antenna CR node …

As a promising interference management technique, interference alignment (IA) has been
applied to cognitive radio (CR) networks. However, the received signal-to-interference-plus …

Given channel statistics information, we develop a joint power control (PC) and resource-
allocation (RA) scheme for outage balancing in a multicarrier femto/macro system to …

Wireless communications are particularly vulnerable to eavesdropping attacks due to their
broadcast nature. To effectively deal with eavesdroppers, existing security techniques …
