    Modelling Impulsive Noise in Indoor Powerline Communication Systems
    (Springer Verlag, 2020) Karakuş, Oktay; Kuruoğlu, Ercan E.; Altınkaya, Mustafa Aziz
    Powerline communication (PLC) is an emerging technology that has an important role in smart grid systems. Due to making use of existing transmission lines for communication purposes, PLC systems are subject to various noise effects. Among those, the most challenging one is the impulsive noise compared to the background and narrowband noise. In this paper, we present a comparative study on modelling the impulsive noise amplitude in indoor PLC systems by utilising several impulsive distributions. In particular, as candidate distributions, we use the symmetric alpha-Stable (S alpha S), generalised Gaussian, Bernoulli Gaussian and Student's t distribution families as well as the Middleton Class A distribution, which dominates the literature as the impulsive noise model for PLC systems. Real indoor PLC system noise measurements are investigated for the simulation studies, which show that the S alpha S distribution achieves the best modelling success when compared to the other families in terms of the statistical error criteria, especially for the tail characteristics of the measured data sets.

    The Performance Comparison of European Dttv Standards With Ldpc-Encoded Standard Under Awgn Channel
    (Springer Verlag, 2013) Karakuş, Oktay
    In this study, in addition to previous work which is a performance comparison of European DTTV Broadcasting standards which are known as DVB-T and DVB-T2, DVB-T2's inner encoder/interleaver block which has LDPC Encoder/Bit Interleaver, is integrated into DVB-T instead of its own inner encoder/interleaver block. This Proposed System's performance under AWGN channel is compared to the DVB-T/T2 standards. The Proposed System achieves better performance results according to DVB-T and very close results according to DVB-T2. It achieves nearly from 4 to 7 decibels SNR gain and up to 13 Mb/s data rate gain then DVB-T results according to different code rate and modulation parameters.
