Multihop DF Relaying in NB-PLC System Over Rayleigh Fading and Bernoulli–Laplacian Noise

In this paper, we consider a decode-and-forward relay-assisted multihop power-line communication (PLC) system. The statistics of the end-to-end signal-to-noise ratio (SNR) in the destination are studied considering the Gaussian-distributed background and Laplacian-distributed impulsive noises. Using the statistics of the instantaneous SNR, the performance of the considered narrowband (NB) PLC system is analyzed. Particularly, new expressions are derived for the outage probability and end-to-end average bit-error-rate. Moreover, the average channel capacity is also obtained. The analytical results are corroborated through Monte Carlo simulations.
