Signal-to-noise ratio estimation for M -QAM signals in η ...
Despite raising the mathematical complexity of the SNR estimation problem, general probability distributions, such as the η−μ and κ−μ distributions, model a wider variety of fading signals, such as signals received on Nakagami-m, Hoyt (Nakagami-q), Rice (Nakagami-n), unilateral Gauss, and Rayleigh channels.

Nakagami-m fading distribution is another useful and important model to characterize the fading channel [6]. Kang et al. [7] modeled the OFDM- BPSK system with frequency selective fading channel. Zheng et al. [8] further enhanced the work by presenting asymptotic BER performance of OFDM system in frequency selective Nakagami-m channel....

Performance Estimation of OFDM in Multipath Rayleigh ...
The data are sent over parallel sub-channels with each sub-channel modulated by a modulation scheme such as BPSK, QPSK, and 16 QAM etc. The advantage of OFDM is its ability to cope with severe channel conditions compared to a single carrier modulation scheme but still maintaining the data rates of a conventional scheme with the same bandwidth....

The system performance is analyzed under Nakagami-m fading channels by varying the m values as 0.5, 0.8, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5, with the average received power Ω set to unity. Moreover, the system is tested under the effects of Rayleigh and Rician multipath fading channels, with the number of contributing paths altered as 5 and 10 ......

Recently, in 9 and 10, the authors reported the potential for using the discrete‐Fourier transform (DFT) spread OFDM as a potential 5G waveform candidate, with expected benefits being flexibility, spectrum, latency, and robustness to fading channels, where the overhead can be tuned with the frequency selectivity of the channel.

If a Nakagami-m channel fading model is considered (i.e., κ → 0 and μ=m), the optimum θ values are confirmed by the values presented in (, Table one) (for QPSK constellations), which confirms the precision of the Lower Bound B approximation. Evaluation of the execution time
