“…In [15], a statistical model for the PLC channel impulse response was derived from the statistics of the delay spread and the attenuation of the set of measured channels that was presented in [16]. Conversely, the channel generation in the frequency domain was addressed in [17]. Basically, the method generates channel responses that show the same distribution of peaks and notches of the measured channels.…”

Abstract-The characteristics of the power line communication (PLC) channel are difficult to model due to the heterogeneity of the networks and the lack of common wiring practices. To get the full variability of the PLC channel, random channel generators are of great importance for the design and testing of communication algorithms.In this respect, we propose a random channel generator that is based on the top-down approach. Basically, we describe the multipath propagation and the coupling effects with an analytical model. We introduce the variability into a restricted set of parameters, and, finally, we fit the model to a set of measured channels. The proposed model enables a closed-form description of both the mean path loss profile and the statistical correlation function of the channel frequency response.As an example of application, we apply the procedure to a set of in-home measured channels in the band 2-100 MHz whose statistics is available in the literature. The measured channels are divided into nine classes according to their channel capacity. We provide the parameters for the random generation of channels for all nine classes, and we show that the results are consistent with the experimental ones.Finally, we merge the classes to capture the whole heterogeneity of in-home PLC channels. In detail, we introduce the class occurrence probability, and we present a random channel generator that targets the ensemble of all nine classes. The statistics of the composite set of channels is also studied, and it is compared to the results of experimental measurement campaigns in the literature.

“…Different experimental investigations reported the PLC channel as a rich multipath propagation channel, due to the multiple branches present in a classical electrical network and to the impedance mismatch occurring at the network terminations (outlets) and nodes [20][21][22][23]. This similarity of the PLC channel with wireless channels suggests promising results when applying TR to PLC.…”

Power Line Communication (PLC) is the response for nowadays high demand of multimedia services in domestic environment, not only for its fast and reliable transfer characteristics but also for its flexible low cost implementation, since the PLC technology uses the existing electrical network infrastructure and the omnipresent outlets throughout the home. The transfer of such a high bit rate through the mains network generates acceptable radiated emission regulated by international standards, but the increment in speed for new generation PLC may cause higher levels of emissions. This paper explains the use of the Time Reversal (TR) technique to mitigate radiated emissions from PLC systems. This method was probed experimentally in real electrical networks with excellent results: in 40% of the observations, the Electromagnetic Interference (EMI) generated by PLC transmission could be reduced by more than 3 dB, and this EMI mitigation factor could increase to more than 10 dB in particular configurations.

“…The random and sudden state transients in electromagnetic conditions, such as the unpredictable activities of marine creatures (such as shrimps) in acoustic communications [10,28], or the appliance electric switching or other uncoordinated transmissions in PLC systems [12,29], will probably lead to impulsive noise. The resulting impulsive noises, despite the sparsity in the time domain, usually have the extremely strong power, which will significantly degrade the transmission performance of OFDM systems that are sensitive to amplitude distortions.…”

In radar and sonar networks, heavy clutter and noise have generated strong impairments to information transmission and processing. Coding techniques have been widely used to cope with various channel noises and thereby to improve transmission performance. In the study, we investigate a novel cascaded coding scheme for systems operating in adverse electromagnetic environments, e.g., underwater acoustic communications (UAC), where the impulsive noise will be inevitable and the bit error ratio (BER) of receiver will be deteriorated greatly. Our cascaded encoding scheme employs the polar code as inner code while the Luby transform (LT) code as outer code. Inspired on a novel conception of channel polarization, the polar code uses a group of idea sub-channels to carry the useful information, while let other bad sub-channels bear no information. By cascading the outer LT code which accomplishes some parity check to the input of inner code, the performance of inner polar code is improved, as the decoding of polar code relies on a successive cancelation technique which is relatively sensitive to initial input. Error correcting performance of the new cascaded code is studied under impulsive noise characterized by a Middleton Class-A model. Simulations validate the proposed cascaded coding scheme. Compared with the popular low-density parity check (LDPC) code, the cascaded scheme can significantly improve the BER performance in the presence of impulsive interference, which also surpasses another cascaded code that is proved to be effective in impulsive noise channel, i.e., cascaded LDPC and LT coding scheme.
