Next Generation M2M Cellular Networks: Challenges and Practical Considerations
Abdelmohsen Ali, Walaa Hamouda, Murat Uysal
In this article, we present the major challenges of future machine-to-machine (M2M) cellular networks such as spectrum scarcity problem, support for low-power, low-cost, and numero…
Spectrum Monitoring Using Energy Ratio Algorithm For OFDM-Based Cognitive Radio Networks
Abdelmohsen Ali, Walaa Hamouda
This paper presents a spectrum monitoring algorithm for Orthogonal Frequency Division Multiplexing (OFDM) based cognitive radios by which the primary user reappearance can be detec…
Low Power Wideband Sensing for One-Bit Quantized Cognitive Radio Systems
Abdelmohsen Ali, Walaa Hamouda
We proposes an ultra low power wideband spectrum sensing architecture by utilizing a one-bit quantization at the cognitive radio (CR) receiver. The impact of this aggressive quanti…
Entangled squeezed states in noncommutative spaces with minimal length uncertainty relations
Sanjib Dey, Véronique Hussin
We provide an explicit construction of entangled states in a noncommutative space with nonclassical states, particularly with the squeezed states. Noncommutative systems are found…
Hedging of defaultable claims in a structural model using a locally risk-minimizing approach
Ramin Okhrati, Alejandro Balbás, José Garrido
In the context of a locally risk-minimizing approach, the problem of hedging defaultable claims and their Follmer-Schweizer decompositions are discussed in a structural model. This…
Off-resonant polarized light-controlled thermoelectric transport in ultrathin topological insulators
M. Tahir, P. Vasilopoulos
We study thermoelectric transport in ultrathin topological insulators under the application of circularly polarized off-resonant light of frequency Ω and amplitude A. We derive ana…
