The Role-Relevance Model for Enhanced Semantic Targeting in Unstructured Text
Christopher A. George, Onur Ozdemir, Connie Fournelle +1
Personalized search provides a potentially powerful tool, however, it is limited due to the large number of roles that a person has: parent, employee, consumer, etc. We present the…
Asynchronous Linear Modulation Classification with Multiple Sensors via Generalized EM Algorithm
O. Ozdemir, T. Wimalajeewa, B. Dulek +2
In this paper, we consider the problem of automatic modulation classification with multiple sensors in the presence of unknown time offset, phase offset and received signal amplitu…
Permutation Trellis Coded Multi-level FSK Signaling to Mitigate Primary User Interference in Cognitive Radio Networks
Raghed El-Bardan, Engin Masazade, Onur Ozdemir +2
We employ Permutation Trellis Code (PTC) based multi-level Frequency Shift Keying signaling to mitigate the impact of Primary Users (PUs) on the performance of Secondary Users (SUs…
Hybrid Maximum Likelihood Modulation Classification Using Multiple Radios
Onur Ozdemir, Ruoyu Li, Pramod K. Varshney
The performance of a modulation classifier is highly sensitive to channel signal-to-noise ratio (SNR). In this paper, we focus on amplitude-phase modulations and propose a modulati…
Asymptotic Properties of Likelihood Based Linear Modulation Classification Systems
Onur Ozdemir, Pramod K. Varshney, Wei Su +1
The problem of linear modulation classification using likelihood based methods is considered. Asymptotic properties of most commonly used classifiers in the literature are derived.…
