Broadcast erasure channel with feedback: The two multicast case-Algorithms and bounds
(2013)We consider the single hop broadcast packet erasure channel (BPEC) with two multicast sessions (each of them destined to a different group of N users) and regularly available instantaneous receiver ACK/NACK feedback. Using ... -
Coded-reference ultra-wideband systems
(2008)Transmitted-reference (TR) and frequency-shifted reference (FSR) ultra-wideband (UWB) systems employ pairs of reference and data signals, which are shifted in the time and frequency domains, respectively, to facilitate ... -
DC shift based image reconstruction for magnetic particle imaging
(Institute of Electrical and Electronics Engineers Inc., 2017)Magnetic Particle Imaging (MPI) is a new imaging technology that images the spatial distribution of iron oxide nanoparticles. Since the magnetic field strength that can be safely applied in MPI is limited, the field-of-view ... -
Effects of channel state information uncertainty on the performance of stochastic signaling
(2011)In this paper, stochastic signaling is studied for power-constrained scalar valued binary communications systems in the presence of uncertainties in channel state information (CSI). First, it is shown that, for a given ... -
Evaluating spatial diversity technique for mitigating multipath fading of fixed terrestrial point-to-point systems
(Institute of Electrical and Electronics Engineers Inc., 2015)Multipath fading is the dominant propagation factor for fixed terrestrial microwave line-of-sight (LOS) radio links operating at frequencies below 10 GHz. Fading due to multipath propagation attenuates received signals on ... -
An FPGA implementation architecture for decoding of polar codes
(2011)Polar codes are a class of codes versatile enough to achieve the Shannon bound in a large array of source and channel coding problems. For that reason it is important to have efficient implementation architectures for polar ... -
Mikrodizin analizinde gürbüz gen ifadesi elde edebilmek maksadıyla kullanılan ön işleme algoritmalarının karşılaştırılması ve teknik tekrarların başarımlarının analizi
(IEEE (Institute of Electrical and Electronics Engineers), 2006)Preprocessing of microarray data involves the necessary steps of background correction, normalization and summarization of the raw intensity data obtained from cDNA or oligo-arrays before statistical analysis. Several ... -
A new signaling scheme for Underwater Acoustic communications
(IEEE, 2013)Underwater Acoustic (UWA) communications has attracted a lot of interest in recent years motivated by a wide range of applications. Different signaling solutions have been developed to date including non-coherent communications, ... -
Noncoherent space-time coding: an algebraic perspective
(IEEE, 2005-06)The design of space-time signals for noncoherent block-fading channels where the channel state information is not known a priori at the transmitter and the receiver is considered. In particular, a new algebraic formulation ... -
Optimal signaling and detector design for power constrained on-off keying systems in Neyman-Pearson framework
(2011)Optimal stochastic signaling and detector design are studied for power constrained on-off keying systems in the presence of additive multimodal channel noise under the Neyman-Pearson (NP) framework. The problem of jointly ... -
RF radiometery sensor sensitivity and detection profile
(2008)Temperature sensing using microwave radiometry has proven value for non-invasively measuring the absolute temperature of tissues inside the human body. However, current clinical radiometers operate in GHz or infrared ... -
Synchronization and chaotic masking scheme based on occasional coupling
(American Physical Society, 2000)Synchronization and a related message transmission scheme using synchronized chaotic systems was presented for discrete-time systems. The scheme was based on occasional coupling of transmitter and receiver systems. The ...
