Discrete fourier transform spread zero word OFDM
Nemati, Mahyar; Takshi, Hengameh; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2017)Fifth generation (5G) waveform must meet a superior performance in multipath channels along with low peak to average power ratio (PAPR), especially in up-link transmission. Among waveform candidates, zero tail (ZT) DFT-spread ... -
A flexible hybrid waveform
Nemati, Mahyar; Takshi, Hengameh; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2017)Cellular systems of fifth generation (5G) require a waveform with flexible guard interval length along with a low power consumption. Different cyclic prefix (CP) durations in long term evolution (LTE) result in loss of ... -
Low ICI symbol boundary alignment for 5g numerology design
Nemati, Mahyar; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2018)Symbol boundary alignment, with respect to waveform selection, has an important impact on the numerology design for fifth-generation mobile applications. The current symbol boundary alignment, along with orthogonal frequency ... -
A novel one-base station hybrid positioning method
Takshi, Hengameh; Nemati, Mahyar; Arvas, Ercüment; Baykaş, Tunçer (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 ... -
