N-continuous OFDM with CP alignment
Güvenkaya, Ertuǧrul; Şahin, Alphan; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers, 2015)In this paper, we propose an out-of-band (OOB) reduction method which incorporates with multipath channel and N-continuous OFDM structure. By exploiting the inevitable guard periods between OFDM symbols, i.e., cyclic prefix ... -
A practical physical-layer security method for precoded OSTBC-based systems
Hamamreh, Jehad M.; Güvenkaya, Ertuǧrul; Baykaş, Tunçer; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers, 2016)In this work, we investigate the security performance obtained by employing a practical precoded orthogonal space time block coding method (POSTBC) in MISO wireless networks. In particular, space time codewords are precoded ... -
Secure communication in frequency selective channels with fade-avoiding subchannel usage
Güvenkaya, Ertuǧrul; Arslan, Hüseyin (IEEE Computer Society, 2014)The random nature of fading channels is an enabling factor for achieving secrecy against eavesdropping. By considering the channel frequency selectivity, we propose an adaptive transmission scheme in which the faded ... -
Time-asymmetric and subcarrier-specific pulse shaping in ofdm-based waveforms
Güvenkaya, Ertuǧrul; Bala, Erdem; Yang, Rui; Arslan, Hüseyin (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. ... -
Waveform design principles for 5G and beyond
Elkourdi, Mohamed H.; Peköz, Berker; Güvenkaya, Ertuǧrul; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2016)Various emerging applications in future wireless networks require rethinking the access techniques not only from the capacity perspective but also satisfying a wide variety of requirements under the same framework. Traditional ... -
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
Güvenkaya, Ertuǧrul; Şahin, Alphan; Bala, Erdem; Yang, Rui; Arslan, Hüseyin (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 ...
