Interference cancellation through interference alignment for downlink of cognitive cellular networks
(
Institution of Engineering and Technology
, 2015 , Article)
Interference cancellation through interference alignment (IA) at the downlink of cognitive cellular networks is proposed. IA helps the spatial resources to be shared among primary and secondary cells, and thus it can provide ...
On the Performance of Quickest Detection Spectrum Sensing: The Case of Cumulative Sum
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
Quickest change detection (QCD) is a fundamental problem in many applications. Given a sequence of measurements that exhibits two different distributions around a certain flipping point, the goal is to detect the change ...
Blind SNR Estimation of Gaussian-Distributed Signals in Nakagami Fading Channels
(
IEEE
, 2015 , Article)
A blind (non-data-aided) SNR estimator using the statistical moments of the received signal is proposed. The proposed envelope-based non-data-aided estimator works for any time-domain Gaussian-distributed signal (e.g. OFDM ...
5G Networks Towards Smart and Sustainable Cities: A Review of Recent Developments, Applications and Future Perspectives
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
5G wireless communication systems provide massive system capacity with high data rates, very short low-latency, and ultra-high reliability, in addition to high connection density with a positive experience on smart cities ...
A simple cross correlation switched beam system (XSBS) for angle of arrival estimation
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with ...
Energy-efficient cooperative cognitive relaying schemes for cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
We investigate a cognitive radio network in which a primary user (PU) may cooperate with a cognitive radio user (i.e., a secondary user (SU)) for transmissions of its data packets. The PU is assumed to be a buffered node ...
