Cognitive radio networks
TLDR
This article highlights some of the recent information theoretic limits, models, and design of these promising networks of intelligent, adaptive wireless devices called cognitive radios.Abstract:
In recent years, the development of intelligent, adaptive wireless devices called cognitive radios, together with the introduction of secondary spectrum licensing, has led to a new paradigm in communications: cognitive networks. Cognitive networks are wireless networks that consist of several types of users: often a primary user (the primary license-holder of a spectrum band) and secondary users (cognitive radios). These cognitive users employ their cognitive abilities to communicate without harming the primary users. The study of cognitive networks is relatively new and many questions are yet to be answered. In this article we highlight some of the recent information theoretic limits, models, and design of these promising networks.read more

Cognitive Radio: An Information-Theoretic Perspective
TL;DR: In this paper, the authors consider a communication scenario in which the primary and the cognitive user wish to communicate to different receivers, subject to mutual interference, and characterize the largest rate at which the cognitive radio can reliably communicate under the constraint that no interference is created for the primary user, and the primary encoder-decoder pair is oblivious to the presence of the cognitive radios.

Cognitive Internet of Things: A New Paradigm beyond Connection
TL;DR: This paper proposes an operational framework of CIoT, which mainly characterizes the interactions among five fundamental cognitive tasks: perception-action cycle, massive data analytics, semantic derivation and knowledge discovery, intelligent decision-making, and on-demand service provisioning, and provides a systematic tutorial on key enabling techniques involved in the cognitive tasks.

The capacity of wireless networks
Piyush Gupta,P. R. Kumar +1 more
TL;DR: When n identical randomly located nodes, each capable of transmitting at W bits per second and using a fixed range, form a wireless network, the throughput /spl lambda/(n) obtainable by each node for a randomly chosen destination is /spl Theta/(W//spl radic/(nlogn)) bits persecond under a noninterference protocol.

Writing on dirty paper (Corresp.)
TL;DR: It is shown that the optimal transmitter adapts its signal to the state S rather than attempting to cancel it, which is also the capacity of a standard Gaussian channel with signal-to-noise power ratio P/N.

The Capacity Region of the Gaussian Multiple-Input Multiple-Output Broadcast Channel
TL;DR: A new notion of an enhanced broadcast channel is introduced and is used jointly with the entropy power inequality, to show that a superposition of Gaussian codes is optimal for the degraded vector broadcast channel and that DPC is ideal for the nondegraded case.
