Electric field representation of pulsar intensity spectra [PDF]
, 2005 Pulsar dynamic spectra exhibit high visibility fringes arising from interference between scattered radio waves. These fringes may be random or highly ordered patterns, depending on the nature of the scattering or refraction.

The MIMO-OTFS Technique in the Next 6G Communications
Engineering AccessThe orthogonal time-frequency space (OTFS) technique is a promising method of waveform modulation that encodes data in the delay-doppler (DD) domain. OTFS distinguishes itself from conventional multiplexing methods by employing two-dimensional modulation

Measurement-Based Delay and Doppler Characterizations for High-Speed Railway Hilly Scenario
International Journal of Antennas and Propagation, 2014 This paper presents results for delay and Doppler spread characterization in high-speed railway (HSR) hilly scenario. To investigate the propagation characteristics in this specific terrain, a measurement campaign is conducted along the “Guangzhou ...

On the Use of a Two-Dimensional Cyclic Prefix in OTFS Modulation and Its Implications
IEEE Open Journal of the Communications SocietyIn this manuscript we investigate the implications of adopting a double cyclic prefix in the orthogonal time-frequency space modulation. Our study first focuses on the analysis of the modulated signal and on the development of a useful model for the ...

Multipath Parameter Estimation from OFDM Signals in Mobile Channels
, 2010 We study multipath parameter estimation from orthogonal frequency division multiplex signals transmitted over doubly dispersive mobile radio channels. We are interested in cases where the transmission is long enough to suffer time selectivity, but short ...
