“…SD is chosen as 400 m and 800 m, respectively, in consistence with a small PLC system environment [2]. Depending on the power distribution network, in general, σ hi lies in between 2 dB to 5 dB [4]. Here we assume σ hi = 3 dB, ∀i, where the conversion from absolute scale to dB scale is given by σ hi (dB) = 10σ hi / ln 10.…”

In this paper, an incremental selective decode-andforward (ISDF) relay strategy is proposed for power line communication (PLC) systems to improve the spectral efficiency. Traditional decode-and-forward (DF) relaying employs two time slots by using half-duplex relays which significantly reduces the spectral efficiency. The ISDF strategy utilizes the relay only if the direct link quality fails to attain a certain information rate, thereby improving the spectral efficiency. The path gain is assumed to be log-normally distributed with very high distance dependent signal attenuation. Furthermore, the additive noise is modeled as a Bernoulli-Gaussian process to incorporate the effects of impulsive noise contents. Closed-form expressions for the outage probability and the fraction of times the relay is in use, and an approximate closed-form expression for the average bit error rate (BER) are derived for the binary phase-shift keying signaling scheme. We observe that the fraction of times the relay is in use can be significantly reduced compared to the traditional DF strategy. It is also observed that at high transmit power, the spectral efficiency increases while the average BER decreases with increase in the required rate.

“…This multiplicative noise significantly attenuates the useful signal but does not have any influence on the noise. Various efforts have been made by researchers to characterize PLC channels . The PLC channel measurements performed in the work of Tlich et al over a frequency range of 30 kHz to 100 MHz in various indoor channel environments suggest that the peak and notch widths of the measured transfer functions are Rayleigh distributed.…”

“…Various efforts have been made by researchers to characterize PLC channels. [15][16][17][18][19][20][21] The PLC channel measurements performed in the work of Tlich et al 17 over a frequency range of 30 kHz to 100 MHz in various indoor channel environments suggest that the peak and notch widths of the measured transfer functions are Rayleigh distributed. The multipath PLC channel measurements conducted in the work of Tan and Thompson 18 over a 30-MHz bandwidth also support that the magnitude of the PLC channel gain follows a Rayleigh distribution.…”

“…Besides Rician and Rayleigh channel models, it has also been proposed that the path amplitude of the PLC channel follows the Log-normal distribution. 20,21 Contributions: In this paper, PLC system performance is studied under the influence of Rayleigh channel and additive noises, namely, Nakagami-m background noise and Middleton class A distributed impulsive noise. The BER and outage probability of PLC system over Rayleigh distributed channel gain and Nakagami-m background noise was evaluated in the work of Mathur et al 22 However, the phase of the background noise was assumed to be uniform, and the BER was not expressed in closed form.…”

Owing to its huge potential to provide easy access to high‐speed video and data, power line communication (PLC) has recently grabbed the attention of the researchers. The PLC is an emerging field of communication for the home area network of smart grid. Because power lines were not initially designed for communication purposes, they offer a difficult communication environment in the form of impulsive noise and multiplicative noise, in addition to the background noise. This elucidates the need for evaluating the performance of PLC systems by taking into account all these factors. The performance of a PLC system under the influence of Rayleigh distributed channel gain, background noise (with nonuniform phase), and impulsive noise is comprehensively studied in this paper. We evaluate closed‐form expressions of the average bit error rate and outage probability for different cases depending on the presence or absence of impulsive noise and channel gain. We provide a further insight into the system by obtaining the diversity of the PLC system. Simulation results closely match with our analysis, thereby establishing the validity of the derived expressions.
