Performance Evaluation of OTFS and OFDM in Rayleigh Fading Channel

Journal of Engineering, Volume 2026, Issue 1, 2026.
Orthogonal time–frequency space (OTFS) modulation is a crucial technology for addressing the challenges of 5G and 6G networks. OTFS was developed to address the problems of signal weakness and quality loss in mobile environments, such as those experienced by a user in a fast‐moving car or train; this is achieved by reducing intercarrier interference ...

Experimental characterization of nonlinear interference noise as a process of intersymbol interference [PDF]

Optics Letters, 2018
We demonstrate a method for experimentally characterizing the second order statistics of nonlinear interference noise (NLIN) as an intersymbol interference (ISI) process. The method enables measurement of the properties of high-order ISI coefficients, which have been largely overlooked in the past.
