Performance Analysis of OFDM-IM Systems over Generalized $\kappa-\mu$ and $\eta-\mu$ Fading Channels
2022 Second International Conference on Next Generation Intelligent Systems (ICNGIS)(2022)
Abstract
In this paper, average bit error rate (ABER) performance of an orthogonal frequency division multiplexing with index modulation (OFDM-IM) system, which is a strong transmission technology candidate for next-generation networks, has been analyzed over generalized fading models, namely eta-mu
$(\eta-\mu)$
and kappa-mu
$(\kappa-\mu)$
fading channels. These models have the advantage of simple algebraic notation, line-of-sight (LOS) and non-line-of-sight (NLOS) propagation effects. The
$\kappa-\mu$
fading channel model is a LOS distribution, that includes the Nakagami-m and the Rice (Nakagami-n) distributions. Similarly, the special cases of
$\eta-\mu$
fading channel model are Hoyt, Rayleigh, Nakagami-m and One-sided Gaussian distributions. The effect of
$\eta-\mu$
and
$\kappa-\mu$
fading channel characteristics on the ABER performance of OFDM-1M systems was shown via computer simulations.
