%T SEFDM: Spectral Efficiency Upper Bound and Interference Distribution
%X This work explores the statistical model for a 5G
and beyond (5GB) multi-carrier signal candidate; spectrally
efficient frequency division multiplexing (SEFDM), in which the
orthogonality between its subcarriers is intentionally violated
compared to conventional orthogonal frequency division multiplexing
(OFDM). A mathematical model describing the statistical
characteristics of inter-carrier interference (ICI) is derived and
verified through system model simulations. Results show that the
ICI is of normal distribution, whose variance is dependent on
both the level of bandwidth compression and on the signal level.
Models developed are used to derive the error bounds of SEFDM
signals in Gaussian noise channels, as well as the upper bound
of SEFDM spectral efficiency
