“…Rayleigh, Nakagami‐ m , Rician, and Weibull) do not precisely match practical measurements. Accordingly, it is critically important to correctly characterize the wireless channel environment in theory 5–14 . For this reason, different channel models representing many different channel environments have been presented in the literature.…”

Summary This study presents the average symbol error probability (ASEP) performance of a single‐input single‐output communication with imperfect phase error (IPE) and without IPE over the Beaulieu‐Xie fading channels. The Beaulieu‐Xie fading model is proposed recently and it is a popular characterization for the line‐of‐sight and non‐line‐of‐sight environments. The proposed theoretical analysis, which is based on the probability density function, is enough general and applicable in some real‐life scenarios. For both cases, closed‐form exact, approximate, and asymptotic expressions are derived for the ASEP of different modulation types. Finally, exact simulations have been introduced to confirm the accuracy of the theoretical findings obtained and present insights into the considered scheme performance.

“…As a different QAM scheme, hexagonal QAM (HQAM) analysis for a two‐ray relaying network by employing adaptive physical layer coding was proposed 23 . The same QAM scheme for MIMO TAS/MRC system over Weibull channels was studied in Reference 24. Most recently, the error performance of HQAM, RQAM, or XQAM for different systems has been investigated in References 25‐29.…”

“…Although the results from References 19‐35 are insightful, these studies fall short in analyzing the QAM schemes for body‐centric communications and in modeling bimodality characteristics in a wireless link. Moreover, as a significant fading model, the alternate Rician shadowed (ARS) fading environments in a system has not been investigated in the aforementioned literature.…”

Quadrature amplitude modulation (QAM) techniques are employed for various communication systems due to its advantages such as efficient bandwidth and high rate. In this paper, the average symbol error rate (ASER) performances of single‐input single‐output networks are investigated to address the different QAM schemes combined use. The link in the network experiences the alternate Rician shadowed (ARS) fading which has the benefit of contributing left or right‐sided bimodality. Four different QAM schemes such as rectangular QAM, cross‐QAM, hexagonal QAM, and square QAM are used for the considered network. Under these assumptions, new closed‐form expressions for the ASER in terms of elementary functions and Meijer's G functions are derived. The derived ASER expressions are obtained by employing the Prony approximation with two terms which has fractional coefficients to provide precise results. Based on the second‐order exponential function approximation for Gaussian Q‐function, the ASER expressions of the considered system are also proposed. Additionally, we provide other important engineering insights based on the high signal‐to‐noise‐ratio analysis of the ASER performance over ARS fading channels. Finally, all our theoretical results are confirmed with simulations.

“…Specifically, IoT (Internet of Things) technology which is one of the backbones of industrial systems has been recently combined to VLC systems to provide energy efficiency [19]. Moreover, channel modelling and indoor positioning are very attractive issues for VLC systems such as RF systems (20)(21)(22)(23).…”

Visible light communication (VLC) technology has arisen as promising candidate to solve the critical challenges of wireless communication networks. In particular, the evolving explosion in use of internet services requiring high bandwidth will soon become a great potential problem among the service provider. Meanwhile, this paper describes a physical layer solution to provide data transmission in the VLC networks. In the paper, it is aim to examine the performance comparison of SC-PPM (Subcarrier Pulse Position Modulation) demodulator schemes. It is considered three receiver techniques to assemble the demodulator techniques to SC-PPM receiver system. Firstly, the traditional PPM (T-PPM) demodulator has been applied on the SC-4PPM receiver system to estimate the slot that includes high frequency signal that is referred to as subcarrier signal. To successfully detect the bits by using traditional PPM receiver, it must be known the dimming level of received SC-4PPM signal. This is a serious problem to ensure data transmission in the real-time VLC systems due to challenge of providing the variable dimming level knowledge at the receiver side. In another receiver model that is referred to as PD (Peak Detector), it is aim to detect peak values of slot with high frequency signal. The disadvantage of this system is that BER (Bit Error Rate) performance depends the difference between peak and bottom values of subcarrier filled slot. Hence, second method is improved to achieve the similar BER performance at all dimming levels between 12.5% and 87.5%. This receiver model is called as IPD in the paper
