Spectrum Sharing for Unlicensed Bands

by Raul Etkin, Abhay Parekh, David Tse - in IEEE DySPAN 2005 , 2005
"... We study a spectrum sharing problem in an unlicensed band where multiple sys-tems coexist and interfere with each other. Due to asymmetries and selfish system behavior, unfair and inefficient situations may arise. We investigate whether efficiency and fairness can be obtained with self-enforcing spe ..."

Auction-based spectrum sharing

by Jianwei Huang, Randall Berry, Michael L. Honig - WiOpt '04 , 2004
"... Abstract. We study auction-based mechanisms for sharing spectrum among a group of users, subject to a constraint on the interference temperature at collocated receivers. The users access the channel using spread spectrum signaling and thus generate interference with each other. Each user receives a ..."

"... Abstract Efficient spectrum-sharing mechanisms are crucial to alleviate the bandwidth limitation in wireless networks. In this paper, we consider the following question: can free spectrum be shared efficiently? We study this problem in the context of 802.11 or WiFi networks. Each access point (AP) ..."

Cognitive radios for spectrum sharing

by Anant Sahai, Shridhar Mubaraq Mishra, Rahul T, Kristen Ann Woyach - IEEE Signal Processing Mag , 2009
"... Wireless systems require spectrum to operate, but interference is likely if radios in physical proximity simultaneously operate on the same band. Therefore, spectrum is a potentially scarce resource; across the planet today, spectrum is regulated so that most bands are allocated exclusively to a sin ..."
Abstract - Cited by 8 (2 self) - Add to MetaCart
feasible within the next 5-10 years, Cognitive Radio is about making such radios smart enough to share spectrum and reduce the regulatory overhead. This is an impending wireless revolution that draws upon many signal-processing areas including robust detection, sensor networks, as well as the design

TOWARDS EFFICIENT SPECTRUM SHARING

by Borivoje Nikolic
"... Abstract-One hundred years of spectrum sharing based on reuse the frequency bands that the primary users are not fixed frequency allocations have led to fracturing and poor using at a particular time and a particular location. The utilization. Present methods of frequency allocation combined termina ..."

Spectrum Sharing in the Gray Space

by Jon Peha
"... There has been considerable effort to let more wireless devices operate in “white space ” spectrum, i.e. within frequency bands and geographic areas where no wireless devices are active. Making white space available is certainly useful, but there are other sharing opportunities as well, some of whic ..."

Spectrum sharing in Cognitive Radio Networks

by Haobing Wang, Lin Gao, Xiaoying Gan, Xinbing Wang, Ekram Hossain - in IEEE 27th Conference on Computer Communications , 2008
"... Abstract — We consider the problem of cooperative spectrum sharing among a primary user and multiple secondary users, where the primary user selects a proper set of secondary users to serve as the cooperative relays for its transmission. In return, the primary user leases portion of channel access t ..."

Spectrum sharing with distributed interference compensation

by Jianwei Huang, Randall A. Berry, Michael L. Honig - IN PROC. OF IEEE DYSPAN , 2005
"... We consider a spectrum sharing problem in which each wireless transmitter can select a single channel from a set of available channels, along with the transmission power. An Asynchronous Distributed Pricing (ADP) scheme is proposed, in which users exchange “price ” signals, that indicate the negativ ..."
