Primary user detection in IEEE 802.15.4a based wireless sensor networks
(2013)
Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with ...
MP-SAGE based channel estimation for underwater cooperative OFDM systems
(2013)
In this paper, an efficient ehannel estimation algorithm is proposed fOl' amplify-And-forward (AF) eooperative relay based orthogonal fl'equency division multiplexing (OFDM) system in the presenee of sparse underwater ...
A new technique for OFDM: OFDM-index modulation
(2013)
In this study, a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme, the information is conveyed not only by only M-Ary ...
THE CULTURE OF MULTICULTURALISM AND RACIALIZED ART
(Berghahn Journals, 2013)
This article invites scholars of race and migration to look at the visual arts more closely within the framework of comparative race theory. We argue that within a neoliberal multicultural context, the marketing of art ...
