An OFDM signal identification method for wireless communications systems
(Institute of Electrical and Electronics Engineers, 2015)
Distinction of orthogonal frequency-division multiplexing (OFDM) signals from single-carrier signals is highly important for adaptive receiver algorithms and signal identification applications. OFDM signals exhibit Gaussian ...
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers, 2015)
Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ...
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we introduce a windowing technique, which provides optimal time-frequency containment and maximal adjacent channel interference (ACI) rejection for orthogonal frequency-division multiplexing (OFDM)-based ...
Time-asymmetric and subcarrier-specific pulse shaping in ofdm-based waveforms
(Institute of Electrical and Electronics Engineers, 2015)
In orthogonal frequency-division multiplexing (OFDM) systems, suppressing the out-of-band (OOB) emission with pulse shaping comes with a price. The expense emerges in designing the transition between consecutive symbols. ...
Theoretical analysis of the co-existence of LTE-A signals and design of an ML-SIC Receiver
(Institute of Electrical and Electronics Engineers, 2015)
The increasing number of mobile devices and the demand for large throughput requiring applications has hampered access to the limited frequency spectrum. The goal of this work is to introduce a new degree of freedom to the ...
