Throughput maximization via adjusting packet size of a buffered cognitive radio user
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate a cognitive scenario with one secondary user and one primary user. Users are assumed to be buffered terminals. Each user has certain arrival rate with certain packet size. We propose a scheme ...
On the design of relay-assisted primary-secondary networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ...
Estimating the number of sources in white Gaussian noise: Simple eigenvalues based approaches
(
Institution of Engineering and Technology
, 2017 , Article)
Estimating the number of sources is a key task in many array signal processing applications. Conventional algorithms such as Akaike's information criterion (AIC) and minimum description length (MDL) suffer from underestimation ...
Analysis of In-band Full-Duplex OFDM Signals Affected by Phase Noise and I/Q Imbalance
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The idea of the simultaneous transmission and reception of data using the same frequency is a potential candidate to be deployed in the next generation wireless communications standard 5G. The In-Band Full-Duplex (IBFD) ...
Joint security and energy efficiency in iot networks through clustering and bit flipping
(
Institute of Electrical and Electronics Engineers Inc.
