Peer-to-peer multipoint video conferencing with layered video
(Elsevier, 2011-01)
A peer-to-peer (P2P) architecture for multipoint video conferencing using layered video coding at the end hosts is proposed. The system primarily targets end points with low bandwidth network connections and enables them ...
Design and fabrication of high-frequency ultra-wideband 1D CMUT arrays for acoustic angiography applications - preliminary results
(IEEE, 2018-12-20)
For superharmonic imaging applications involving the use of microbubble contrast agents, transducers that can transmit energy at low frequencies (less than 5 MHz) to excite the microbubbles, and at the same time detect ...
Blood coagulation time measurement using a 1μL of whole blood on a TE mode BAW resonator
(IEEE, 2018-12-20)
This paper presents a possible way to blood coagulation time measurement using a TE (Thickness Extensions) mode BAW (Bulk Acoustic Wave) resonator which requires as low as 1 micro-liter of whole blood. The blood sample is ...
Performance of OFDM-based adaptive visible light communications
(IEEE, 2017)
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
Single photon avalanche diode (SPAD) VLC system and application to downhole monitoring
(IEEE, 2014)
In this paper, it is demonstrated for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively addressed by the use of visible light communication (VLC). As a reliable, ...
The impact of location errors on achievable rates in OFDM-based multi-user visible light communication systems
(IEEE, 2014)
Visible light communication (VLC) is a communication technology in which data is transferred by modulating the visible light intensity. VLC signals degrade significantly due to the absence of the line of sight (LOS) between ...
Kuvvetlendir-ve-aktar tipi işbirlikli haberleşme sistemlerinde zaman senkronizasyonu
(IEEE, 2010)
The synchronization problem in wireless communication systems becomes more important especially in cooperative communication systems than it is for other diversity systems because all terminals in the cooperation use their ...
Fast parallel prefix logic circuits for n2n round-robin arbitration
(Elsevier, 2012-08)
An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ...
End-to-end performance of mixed RF/FSO transmission systems
(IEEE, 2013-11)
In this paper, we consider a heterogenous scenario where free-space optical (FSO) and radio-frequency (RF) technologies are deployed together as a dual-hop communication system, and we investigate the end-to-end outage ...
Generalized maximum-likelihood sequence detection for photon-counting free space optical systems
(IEEE, 2010-12)
We investigate detection methods for on-off keying (OOK) photon-counting Free Space Optical (FSO) systems in the presence of turbulence-induced fading, assuming no channel state information at the receiver. To recover the ...
