Enhanced physical layer security by OFDM signal transmission in fractional Fourier domains
(Institute of Electrical and Electronics Engineers, 2015)
The main idea of physical layer security for wireless communications is making the transmitted signal as meaningless for eavesdroppers. It can be achieved by signal processing techniques. In this study, fractional Fourier ...
A novel one-base station hybrid positioning method
(Institute of Electrical and Electronics Engineers Inc., 2017)
In wireless networks, the need for accurate and low complexity localization methods are growing. Although many positioning methods based on signals' time difference of arrival (TDOA) and angle of arrival (AOA) have been ...
Sentiment analysis based churn prediction in mobile games using word embedding models and deep learning algorithms
