Noncoherent Multiuser Chirp Spread Spectrum: Performance with Doppler and Asynchronism
Nozhan Hosseini, David W. Matolak
In this paper, we investigate multi user chirp spread spectrum with noncoherent detection as a continuation of our work on coherent detection in [1]. We derive the analytical bit e…
EMR: A New Metric to Assess the Resilience of Directional mmWave Channels to Blockages
Fatih Erden, Ozgur Ozdemir, Ismail Guvenc +1
Millimeter-wave (mmWave) communication systems require narrow beams to increase communication range. If the dominant communication direction is blocked by an obstacle, an alternati…
DFT-spread-OFDM Based Chirp Transmission
Alphan Sahin, Nozhan Hosseini, Hosseinali Jamal +2
In this study, we propose a framework for chirp-based communications by exploiting discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM). We sho…
Multicarrier Spectral Shaping for Non-White Interference Channels: Application to L-band Aviation Channels
Hosseinali Jamal, David W. Matolak
In this paper, we investigate an algorithm to attain additive white Gaussian noise (AWGN) performance in spectrally non-white channels, using multicarrier communications, i.e., ort…
Advanced Physical-Layer Technologies in VHF Data Link Communications
Hosseinali Jamal, David W. Matolak
Due to the rapidly increasing number of flights and high usage of VHF channels, the VHF spectrum is becoming much more crowded, and use of analog waveforms will likely not maintain…
Attenuation of Several Common Building Materials in Millimeter-Wave Frequency Bands: 28, 73 and 91 GHz
Nozhan Hosseini, Mahfuza Khatun, Changyu Guo +5
Future cellular systems will make use of millimeter wave (mmWave) frequency bands. Many users in these bands are located indoors, i.e., inside buildings, homes, and offices. Typica…
