Performance analysis of a PLC system over log-normal fading channel and impulsive noise

Performance analysis of power line communication systems with diversity combining under correlated lognormal fading and Nakagami noise

“…Measurements performed over low‐voltage and medium‐voltage PLC channels in [16–18] supported the findings pertaining to lognormal statistics. The lognormal model has been applied in numerous recent references that targeted the performance analysis of PLC systems [8, 19–22]. While the authors of [8] targeted the performance of single‐channel systems under the Nakagami background noise, the authors of [19–22] tackled the performance under the Bernoulli‐Gaussian impulsive noise.…”

“…Since fading constitutes a dominant impairment in PLC systems, diversity combining techniques were advised for these systems [19, 20–24]. In this context, the information‐bearing signal propagates over multiple channels and the received signals are combined for the sake of enhancing the fidelity of signal reconstruction.…”

“…Finally, while the authors of [5–13] are limited to single‐channel systems, our results are extended to two‐channel systems as well, which induces a non‐negligible level of complexity on the BER derivations. While our work adopts the same lognormal statistical channel model as in [19–22], the considered Nakagami noise model remarkably differentiates the calculation methodology compared with the Bernoulli‐Gaussian noise model. In fact, while the PDF of the latter type of noise can be written as a mixture of Gaussian PDFs, the PDF of the Nakagami‐like noise involves the more complicated Whittaker function rendering all subsequent derivations completely different from what has been proposed in [19–22].…”

Performance Analysis of Parallel Relayed Power Line Communication

“…In [13] a maximum likelihood detector was calculated using the same distribution for background noise and correspondingly bit error rate was computed. In [14] the PLC system performance was analyzed over log-normal fading channel and the outage probability plotted.…”
